Question

solve 5x^2=-45x

Answer 1

try putting all the terms equal to 0 and then factoring out

Answer 2

x^2 = - 9x
x = -9 is the solution

Answer 3

You can't divide each side by x unless you claim x is not equal to 0

Answer 4

hmm i know i didn't divide x, i used inspection.

Answer 5

ah im sorry it appeared as though you did. but you still must include x=0

Answer 6

Can you do it ?

Answer 7

x^2 = -9x

x^2 + 9x = 0

x(x + 9) = 0

now we get two solutions x =0 and x = 9

kiara don't do it my way (the way earlier I posted) walleye is right
