Question

Help please, this is supposed to be done with a calculator but i don’t have one

Answer 1

x = {7, -1}

Explanation:

assuming that you are to find the zeros of the equation you dont need a calculator to do this

you can set both sides to zero

(x - 7) = 0

(x + 1) = 0

and then solve for the zeros

x = {7, -1}

that is your answer
