So just to be clear, equation is: x2 = 2x
I plotted ( y = x2 = 2x ) with the computer, and there are 3 solutions for x.
You might recognize, by intuition, that 22 = 22and figure out that
x = 2 solves the equation, but then again, it might not be so obvious, and then what are the other values of x that solve the equation?
one solution is approximately x = -0.7666647
and the third solution is x = 4.
I don't remember the steps for solving this type of problem.

What is 15 to the power of 2 equals?
15 to the 2nd power or 15 squared equals 15 * 15 which equals 225.
3x squared minus 2x when x equals 5?
You fill in for x and solve the equation3(5)^2 - 2(5)15^2 - 10; now solve
5y squared - 2 y squared equals 6 is a?
i think its 3y squared
X squared plus 6x plus 8 equals 0?
x2 + 6x + 8 = 0 Solve for x.X = -2 or X = -4
How would you solve x squared minus 3x minus 15 equals 0?
3x2 when x = 2 is the answer 3 X 4 = 12 or is the answer (3 X 2)2 = 62 = 36
