Question

x • x = 2x

Answer 1

you might just be able to think about this one like a riddle... what number multiplied by itself is equal to that same number times 2?

What level math is this? Are you supposed to solve it as an equation?

Answer 2

im in 9th grade and yes i have to solve as an equation

Answer 3

Ok, so the left side is x^2 "x squared".

So subtract 2x from both sides to move that term from the right to the left.

x^2 - 2x = 0

Then you can factor the left side.

Answer 4

Factored, it becomes:
x(x-2) = 0

So x can equal 0 or x can equal 2.

Then you always always always ;) want to check your work against the original problem...

x • x = 2x
For x = 0, (0)(0) = 2(0) <<<--- correct
For x = 2, (2)(2) = 2(2) <<< --- correct :)
