What value of x is a solution to x2+2=102

Answer 1

So we have \[x^2+2=102\]
First we want to get the variable on a side by itself. So, we are going to subtract 2 from both sides. This leaves us with: \[x^2=100\]

Now, since it's x^2, we are going to take the SQUARE ROOT of both sides.

Answer 2

102-2 = 100
sqrroot of 100 = answer
