2x%5E2-35=15 Start with the given equation.


2x%5E2=15%2B35 Add 35 to both sides.


2x%5E2=50 Combine like terms on the right side.


x%5E2=%2850%29%2F%282%29 Divide both sides by 2 to isolate x%5E2.


x%5E2=25 Reduce.


x=0%2B-sqrt%2825%29 Take the square root of both sides.


x=5 or x=-5 Simplify


So our answers are x=5 or x=-5

2x^2 – 35 = 15
2x^2 = 50
x^2 = 25
x= sqrt(25) or x= -sqrt(25)
x=5 or x=-5
