6x2 - 30x + 24
6(x2 - 5x + 4)
= 6(x-1) (x-4)
72.
2 (a2 - 12a - 32)
2 (a2 - 6a - 16)
= 2 (a - 8) (a + 2)
73.
5x2 + 20x + 15
5(x2 + 4x + 3)
= 5(x + 1) (x+3)
74.
4x2+ 12x - 16
4(x2 + 3x -4)
= 4(x - 1) (x + 4)
75.
2x2 + 14x + 24
2(x2- 7x + 12)
=2 (x - 3) (x-4)
76.
3y2 - 33y + 54
3(y2- 11y + 18)
= 3 (y - 9) (y - 2)
77.
b3 - 7b2 + 10b
b (b2 - 7b + 10)
= b (b - 5) (b - 2)
78.
x3+ 11x2 - 42x
x (x2 + 11x - 42)
= x (x + 14) (x - 3)
79.
3z3 - 21z2 - 54z
3z (z2 + 7z - 18)
=3z (z + 2) (z - 9)
80.
3x3 - 36x2 + 33x
3x (x2 - 12x +11)
= 3x (x - 1) (x - 11)
81.
x3 + 8x2 + 16x
x (x2 + 18x +16)
= x (x + 4) (x + 4)
82.
2x3y - 12x2y +10xy
2xy (x2 - 6x + 5x)
= 2xy (x - 1) (x - 5)
83.
4a2 - 24ab +32b2
4 (a2 - 6ab +8b2)
= 4 (a - 2b) (a - 4b)
84.
3x3 + 3x2y - 18xy2
3x (x2 + xy - 6y2)
= 3x (x + 3y) (x - 2y)
85.
r²s + 7rs2 - 12s3
s (r² + 7rs +12s²)
= s (r + 3s) (r+4s)
86.
3r3 + 6r²t - 24r t²
3r (r²+ 2rt - 8t²
= 3r (r + 4t) (r - 2t)
87.
X4 - 4x3 - 21x2
x2 (x2 - 4x -21)
= x2 (x + 3) (x - 7)
