Question

The solutions of a quadratic equation are 5 and -1. What is the factored form of a related quadratic function?
a) f(x) = (x - 5)(x + 1)
b) f(x) = (x - 5)(x - 5)
c) f(x) = (x + 5)(x - 1)
d) f(x) = (x + 5)(x + 1)

Answer 1

Answer:

A

Step-by-step explanation:

Given the solutions of a quadratic, say x = a, x = b then the factors are

(x - a) and (x - b) and the function is the product of the factors, that is

f(x) = (x - a)(x - b)

Here the solutions are x = 5 and x = - 1, thus the factors are

(x - 5) and (x - (- 1)), that is (x - 5) and (x + 1), thus

f(x) = (x - 5)(x + 1) → A
