Step-by-step explanation:
Assuming you require g(x) to be factored
g(x) = x² + x - 20
Consider the factors of the constant term ( - 20) which sum to give the coefficient of the x- term ( + 1)
The factors are + 5 and - 4
x² + x - 20 = (x + 5)(x - 4) ← in factored form
To obtain the zeros equate to zero
(x + 5)(x - 4) = 0
equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x - 4 = 0 ⇒ x = 4
