Question

x²+2x-8 What will be the zero of the sum?​

Answer 1

Zero of a equation means a value of the variable that when substituted in the equation, gives the value of the equation as 0. Now, to find the zeros of a given equation, we have to equate the equation with 0. Hence, the two zeros of the quadratic equation ${x^2} - 2x - 8$ are 4 and -2.

Answer 2

Answer:

x²+4x-2x-8

x(x+4)-2(x+4)

(x+4) (x-2)

x=-4

x=2
