To solve the equation: 4x2=100

you would use the inverse operation to get the equation: x2=25
. You would then use the inverse operation to get x = because both values make the equation true when you substitute in for x in the original equation.

5 or -5

are you sure

I apologize for the mistake in my previous response. The correct values for x would be 5 and -5. Thank you for pointing that out.
