1. 5(x^2 +2x6)  3(2+xx^2)
2. 2x^45x(x^3 y) + 2y(5x)
3.Factor 2x^5+6x4+4x^3+12x^2
4. Factor 9y^218y +8
Please help. Thank you!!

1.
5x^2+10x30  (6+3x3x^2)
5x^2+10x30+3x^23x6
8x^2+7x36
2. do this the same way
3.
2x^5+6x^4+4x^3+12x^2
2x^2(x^3+3x^2 + 2x+6)
now, by inspection, we have
2x^2(x^2(x+3) + 2(x+3))
to wind up with
2x^2(x^2+2)(x+3)
4. Looks like a difference of squares, but it's one off. So, tweak it a bit:
9(y^22y+1)1
9(y1)^2  1^2
(3(y1)1)(3(y1)+1)
(3y4)(3y2)
