Re: Solving Quadratics by Factoring and Graphing
Plug into the original equation to check that it equals zero.

Re: Solving Quadratics by Factoring and Graphing
3x^2-12x=0
3*2^2-12*0=0
yup it works

Re: Solving Quadratics by Factoring and Graphing
Nope!
3 (2^2) = 12
- 12* 2 = - 24
12 - 24 does not equal 0

Re: Solving Quadratics by Factoring and Graphing
it should be 3x^3-12x=0 instead of 3x^2-12x=0

Re: Solving Quadratics by Factoring and Graphing
3x(-4+x^2)=0
3x((2+x) (-2+x))=0
x=0
2+x=0
2+-2+x=0+-2
2+-2=0
0+x=0+-2
x=0+-2
0+-2=-2
x=-2
-2+x=0
x=2

Re: Solving Quadratics by Factoring and Graphing
3x((2+x) (-2+x))=0
3*0((2+0)(-2+0)=0
That is correct for 0 now repeat those 2 steps for the other two roots.
