Solve using the square root property?

Question

2x^2 - 35 = 15

2x^2 - 35 = 15 + 0

2 (x-1) (

I'm lost right here, Can you help me

Answer 1

i think you may have started wrong. to solve this i would subtract the 15 over to get 2x^2-50=0

then i would divide a 2 out so it become x^2-25=0

then factor it to become (x+5)(x-5)=0

then based on zero product property, x=5,-5

Answer 2

2x^2 - 35 = 15

2x^2 = 15 + 45

x^2 = 60/2

x = 30^1/2

x = 5.477225575

Answer 3

2x^2 - 35 = 15

2x^2 - 50 = 0

2(x^2 - 25) = 0

2(x+5)(x-5) = 0

x = +5 or -5

I don't know an easier way using the square root property.
