Solve!!!!! PLEASE HELP!!! MKE BRAINLIEST!<br> 2x^2 - 28 = x^2 + 15<br> What is the answer!

padilas [110]

Answer:

x = ± sqrt(43)

Step-by-step explanation:

2x^2 - 28 = x^2 + 15

Subtract x^2 from each side

2x^2-x^2 - 28 = x^2-x^2 + 15

x^2 -28 = 15

Add 28 to each side

x^2 - 28 +28= 15+28

x^2 = 43

Take the square root of each side

sqrt(x^2) = ± sqrt(43)

x = ± sqrt(43)
