solve the quadratic equation for x by factoring.

x^2 - 13x = 0

Answer 1

\[x^{2} - 13x = 0 \]

Answer 2

x² = 13x
x² / x = 13
x = 13

Answer 3

Wolf..you can't really do that...

x^2 = 13x

Subtract 13x from both sides, you get

x^2 - 13x = 0

Now factor, you get

x(x - 13) = 0

Set each factor equal to 0, you get
x = 0 and x = 13.

You cannot divide both sides by x, or you lose a solution of x = 0.

Answer 4

Well I guess I lost a solution.
Actually I wasn't dividing both sides by x. I was reducing the fraction x²/x
multiply top and bottom by 1/x results in x.

Answer 5

thank you guys :)
