Answer 1

A.36-20x+x²
(x- 18)(x -2)

B.-76-40p-p²
- (p -38)(p - 2)

C.y3-12y2-64y
y(y²- 12y - 64)
y(y - 16)(y + 4)

D.6x2+29x+13
6x²+ 3x + 26x + 13
3x(2x + 1)+ 13(2x + 1)
(2x + 1)(3x + 13)

E.8x2+26x+15
8x² + 20x + 6x + 15
4x (2 + 5)+ 3 (2x + 5)
(2x + 5)(4x + 3)

F.10y2+43y+12
10y² + 40y + 3y + 12
10y (y + 4) + 3(y + 4)
(y + 4)(10y + 3)

G.12+4m-5m2
12 - 6 m + 10m - 5m²
6(2- n)) + 5m(2 - m)
(2 - ?)(6 + 5m)

H.6x2-5xy-6y2
6x² - 9xy + 4xy + 6y
3x(2x - 3y) + 2y(2x - 3y)
(2x - 3y)(3x + 2y)

I.15x2-11xy-12y2
15x² -20xy + 9xy - 12y²
5x(3x - 4y) + 3y (3x - 4y)
(3x - 4y)(5x + 3y)
