Question 73325: Factor by grouping.
To write exponents, you may indicate exponents with the ^ symbol located above the number 6 on your keyboard. For example, x4 would be written x^4.
3x + 3y + ax + ay
5(x+y) + 9(x+y)
8x3 - 12x2 + 6x - 9
x3 + x2 + 2x + 2
2x3 - 8x2 - 9x + 36

3X+3Y+AX+AY=3(X+Y)+A(X+Y=(3+A)(X+Y)
5(X+Y)+9(X+Y)=5+9(X+Y)=14(9X+Y)
8X^3-12X^2+6X-9=4X(2X-3)+3(2X-3)=(4X+3)(2X-3)
X^3+X^2+2X=2=X^2(X+1)+2X(X+1)=(X^2+2X)(X+1)
2X^3-8X^2-9X+36=2X^2(X-4)-9(X-4)=(2X^2-9)(X-4)
