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
X squared plus 6x plus 8 equals 0?
x2 + 6x + 8 = 0 Solve for x.X = -2 or X = -4
5y squared - 2 y squared equals 6 is a?
i think its 3y squared
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
What to the second power equals 2?
It is about: 1.4142135622 squared = 2
What is 15 to the power of 2 equals?
15 to the 2nd power or 15 squared equals 15 * 15 which equals 225.
Solve x squared plus 6 equals 5x?
(x-3)(x-2)
How do you solve x squared - x equals 6?
(x-3)(x+2)the answer is x=3
Solve x squared plus 2x - 13 equals 2?
(x - 3)(x + 5)
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
What is 70 to the second power?
70 to the power of 2, or, 70 squared, is 70X70, which equals 4,900
Is y equals x squared 2 plus 5 linear?
No, to be linear, both the power of x and y need to be 1. Since x is squared, the power of x is 2.
What is a squared plus b squared equals c squared when a equals 2 and c equals 6?
b = sqrt32 or 4 root 2
2 plus 3 to the second power x 2 equals?
If 2+3 5s 5 squared is 25 then 25 times 2 equals 50
How do you solve x squared minus 4 equals zero?
So u have the function x2-4=0 Now because 4 is a squared number, its square root is 2 (x+2)(x-2)=0
How do you solve x squared minus ten x plus sixteen equals zero?
Factor it. (x - 8)(x - 2) x = 2, 8
