Answer:

Step-by-step explanation:

x^2 + x^2 = 128                 Normally you don't do this but rewrite the question

1x^2 + 1x^2 = 128

You actually do use 1 + 1 = 2 First time I've ever done that.

2x^2 = 128                         Divide by 2

2x^2/2 = 128 / 2

x^2 = 64                            Take the square root of both sides

sqrt(x^2)= sqrt(64)

x = 8

Answer:

8 =6 since 8 squared is 64 and 64 +64 or 64 times 2 is 128 that’s is your answer.
