2.645 squared equals 7. Save --------- Unclear what you're asking: If x=7, then x^2 (that is, "x squared") equals 49. or If x^2=7, then x equals the square root of 7, or about 2.64575
No, x + x equals 2x. x times x equals x2. (x times x equals x squared.)
x2 - x = 20 x = 5
4, -5
no, because xx=x squared, and x squared is not linear
X squared = x+6 6+x=x squared X=6
Yes, x times x equals x squared.
