Question

The roots of a quadratic equation are -7 and 1. Write an equation that could represent this function. Give your answer in standard form and factored form.

Answer 1

X^2+6X-7=0

Explanation:

To identify the quadratic equation use the following method

(X-a)(X-b)=0

Where

a=-7

b=1

(X+7)(X-1)=0

X^2+7X-X-7=0

X^2+6X-7=0
