Question

solve !!!
xsquared=144

Answer 1

What is the inverse of squaring a number? Taking the square root of that thing.
Take the square root of both sides to get x = sqrt(144)

Answer 2

i got 12

Answer 3

That's the right answer. You can check by plugging back in. 12*12=144

Answer 4

thanks can we do another?

Answer 5

Sure

Answer 6

what about something like
Xsquared -8=0

Answer 7

Like other equations, you want to isolate the x before anything. So you'd add 8 to both sides.

Then you get x^2=8
take the square root of both sides and you get x = sqrt(8) or 2sqrt(2)

Answer 8

i got 2 is that right?

Answer 9

well 2squared is 4 so no, taking the square root of x^2 gives you x.
Taking the square root of 8 gives you \[ \sqrt{4} \sqrt{2} aka ... 2\sqrt{2}\]
