Question

What is the solution to

Answer 1

All my work is shown in the image.

Answer 2

For this case, we must find the solutions of the following quadratic equation:

$x ^ 2-35 = 2x$

Rewriting the form $ax ^ 2 + bx + c = 0$we have:

$x ^ 2-2x-35 = 0$

To factor, we must find two numbers that add -2 and multiply -35.

These numbers are:

-7 and 5

$(x + 7) (x-5) = 0$

Thus, the solutions are:

$x = -7\\x = 5$
