Answer: x^2 + 6x – 7 = 0

The solutions x = -7 and x = 1 can be written as:

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

(Because you find the solution values for x from the brackets e.g (x+7) to get x=-7, dunno how to explain it better sry)

From which you can expand the brackets and find the answer in quadratic form.

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

Expand the brackets

x^2 + 7x – x – 7 = 0

x^2 + 6x – 7 = 0
