- (a+b)2 = a2 + b2 + 2ab.
- (a-b)2 = a2 + b2 – 2ab.
- (a+b)3 = a3 + b3 + 3ab(a+b) = a3 + b3 + 3a2b + 3ab2
- (a-b)3 = a3 – b3 – 3ab(a-b) = a3 – b3 – 3a2b + 3ab2
- a3 + b3 = (a+b)3 – 3ab(a+b)
- a3 – b3 = (a-b)3 + 3ab(a-b)
- a2 – b2 = (a-b)(a+b)

## What is the best method to solve quadratic equations?

**Completing the square** is a method that may be used for any quadratic equation. By adjusting your constant (c), you can create a perfect square on the left side of the equation. A perfect square can be factored into two identical binomials, which you can use to solve for any valid values of x.

## What are the three steps for solving a quadratic equation?

There are three basic methods for solving quadratic equations: **factoring, using the quadratic formula, and completing the square**. To solve a quadratic equation by factoring, Put all terms on one side of the equal sign, leaving zero on the other side.

## What are the 5 examples of quadratic equation?

Examples include:

- 2x² – 64 = 0.
- x² – 16 = 0.
- 9x² + 49 = 0.
- -2x² – 4 = 0.
- 4x² + 81 = 0.
- -x² – 9 = 0.
- 3x² – 36 = 0.
- 6x² + 144 = 0.

## Can every quadratic equation be solved?

1 Answer. **No.** **Every quadratic equation has two solutions and can be factorized**, but as level of difficulty rises, splitting may not be easy and one may tend to use quadratic formula.

## What is B² 4ac called?

The solution for the two roots are calculated from the “**quadratic formula**“: The solution depends on the value of b^{2} – 4ac. This term is called the “discriminant”.

## What are the 3 forms of quadratic functions?

There are three commonly-used forms of quadratics:

- Standard Form: y = a x 2 + b x + c y=ax^2+bx+c y=ax2+bx+c.
- Factored Form: y = a ( x − r 1 ) ( x − r 2 ) y=a(x-r_1)(x-r_2) y=a(x−r1)(x−r2)
- Vertex Form: y = a ( x − h ) 2 + k y=a(x-h)^2+k y=a(x−h)2+k.

## What is quadratic formula class 10th?

➡➡The polynomial of degree two is called quadratic polynomial and equation corresponding to a quadratic polynomial P(x) is called a quadratic equation in variable x. ➡➡Thus, **P(x) = ax2 + bx + c =0, a ≠ 0, a, b, c ∈ R** is known as the standard form of quadratic equation.

## What kind of math is quadratic equations?

Quadratic equations are **polynomials**, meaning strings of math terms. An expression like “x + 4” is a polynomial. They can have one or many variables in any combination, and the magnitude of them is decided by what power the variables are taken to.

## What are the topics in quadratic equation?

Quadratic equations are the polynomial equations of degree 2 in one variable of type **f(x) = ax ^{2} + bx + c where a, b, c, ∈ R and a ≠ 0**. It is the general form of a quadratic equation where ‘a’ is called the leading coefficient and ‘c’ is called the absolute term of f (x).

## What are the basic concepts of quadratic equation?

**An equation of the form ax ^{2} + bx + c = 0, where a > 0 and a, b, c are real numbers, is called a quadratic equation**. The numbers a, b, c are called the coefficients of the quadratic equation. A root of the quadratic equation is a number a (real or complex) such that aa

^{2}+ ba + c = 0.

## What is difference between quadratic and biquadratic?

As nouns the difference between quartic and biquadratic

is that **quartic is (mathematics) an algebraic equation or function of the fourth degree while biquadratic is (mathematics) a biquadratic equation**.

## What is meant by zero polynomial?

**The constant polynomial**. **whose coefficients are all equal to 0**. The corresponding polynomial function is the constant function with value 0, also called the zero map.

## How do you Factorise Biquadratic?

A biquadratic equation is a 4-degree equation without the terms of degree 1 and 3. **To solve a biquadratic equation you have to do a change of variable: z = x ^{2}.**

**Then you have to solve the quadratic equation and finally undo the change**.

## What are some math tricks?

The answer is the three-digit number. 371371 gives you 371 or 552552 gives you 552. A related trick is to take any three-digit number. Multiply it by 7, 11, and 13.Table of Contents.
