How do you solve quadratic equations with quantitative aptitude?
Formulas for Algebra – Quadratic Equation or Algebra Questions – Quantitative Aptitude Quiz
- (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.

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 b2 – 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) = ax2 + 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 ax2 + 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 aa2 + 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 = x2. Then you have to solve the quadratic equation and finally undo the change.
