what is the answer to msquare+4m-21
m^2+4m-21
(m+7)(x-3)
------------------
what is the answer to 2xcube+5xsquare - 12x =0
x(2x^2+5x-12)=0
x(2x^2+8x-3x-12)=0
x(2x(x+4)-3(x+4))=0
x(x+4)(2x-3)=0
x=0 or x=-4 of x=3/2
-------------------------
2ysquare = -3y + 35
2y^2+3y-35=0
2y^2+10y-7y-35=0
2y(y+5)-7(y+5)=0
(y+5)(2y-7)=0
y=-5 or y=7/2
