Answer 2

1) 8(5x + 9y)^2 + 12(5x + 9y)

Answer=  4(5x + 9y) (10x + 8y + 3)

2) (y-x)a + (x-y)b

Answer= (a-b) (y-x)

3) 9(a-2b)^2 + 6(2b-a)

Answer= 3(a-2b) (3a-6b-2)

4) (x+y) (2x+3y) - (x+y) (x+1)

Answer= (x+y) (x+3y-1)

5) a^2x^2 + (ax^2+1)x + a

Answer= (x+a) (ax^2+1)

6) a(a+b-c) - bc

Answer= (a+b) (a-c)

7) x^4 - y^4

Answer= (x^2+y^2) (x+y) (x-y)

8) 3x^4 - 243

Answer= 3(x+3) (x+3) (x-3)

9) 2y^2 - 32x^2

Answer= 2(y+4x) (y-4x)

10) (x-1)^2 - (x-2)^2

Answer= 2x - 3

11) (a^2 - b^2) - a - b

Answer= (a+b) (a-b-1)

12) 9(a+b)^2 - 25(a-2b)^2

Answer= (8a-7b) (-2a+13b)

13) 25 - a^2 - 10a - 25

Answer= (a) (10-a)

14) 36 - z^2 + 16z - 64

Answer= (-2+z) (14-z)

15) (x+y)^2 + 10(x+y) + 25

Answer= (x+y+5)^2

16) (a+b)^2 - 16(a+b) + 64

Answer= (a+b-8)^2

17) 15(x+y)^2 - 26(x+y) + 8

Answer= (5x+5y-2) (3x+3y-4)

18) (a+b)^2 + 10(a+b) + 24

Answer= (a+b+6) (a+b+4)
