Solve these equations for x by factoring:
1) x(x4)=12
2) 2x^3+50x=20x^2
3) 2x^2+x6=0
Thank you for all your help!!!!

Pre calculus? This is stock Algebra II.
put the equations in the form of
ax^2+bx+c=0 then factor.
for instance, c is already in that form.
2x^2+x6=0
(2x3)(x+2)=0
x= 3/2 x=2
do the others the same method.
