Solve the following quadratic equation by factorization: 1. (x - 4)(x + 2) = 0

Solution:

Quadratics or quadratic equations can be defined as a polynomial equation of a second degree, which implies that it comprises of a minimum of one term that is squared. The general form of the quadratic equation is: ax² + bx + c = 0 where x is an unknown variable and a,b,c are numerical coefficients

Given,

(x - 4) (x + 2) = 0

So, either x - 4 = 0

⇒ x = 4

Or, x + 2 = 0

x = - 2

Thus, the roots of the given quadratic equation are 4 and -2 respectively.
