Answer:
Step-by-step explanation:
Equation:
x^3 + 7x^2 - 36
Given that:
x1 = -6
x2 = 2
x3 = z
Let the zeros be,
x + 6, x - 2
Multiplying both of these factors ,
(x + 6) × (x - 2)
x^2 + 6x - 2x - 12
= x^2 + 4x - 12
Dividing the polynomial, x^3 + 7x^2 - 36 with the above quadratic equation,
We get:
x^3 + 7x^2 - 36 ÷ x^2 + 4x - 12
= x + 3
z; x + 3 = 0
x = -3
z = -3
-z = 3
