show the steps to solve using the quadratic formula

Question

x^2+6x-5=35

Leave answers as simplified radicals' if nessacary

Answer 1

Subtract 35 from each side: x²+6x-40=0

Now this factors easily as (x+10)(x-4), bu to use the quadratic formula:

x= [-6 ± sqrt(36+160)]/2 = [-6 ± 14]/2

You finish it and make sure it matches the answer from factoring.
