Question

$c. \: 4 {x}^{2} - 16xy - 3x + 12y \\ \\ f. \: ab + 4a - 3b - 12$




can you please solve this sum please it's urgently plzzzzzzzzzzzzzzzzzzzzzzzzzzzzz best answer must be brainliest help me ??????????????????​

Answer 1

Answer:

Step-by-step explanation:

4x^2-16xy-3x+12y

=4x(x-4y)-3(x-4y)

=(x-4y)(4x-3)

f. ab+4a-3b-12

=a(b+4)-3(b+4)

=(b+4)(a-3)

Answer 2

3.4x^2-16xy-3x+12y
4x(x-4y)-3(x-4y)
(x-4y)(4x-3)

6.ab+4a-3b-12
a(b+4)-3(b+4)
(b+4)(a-3)









1.x^2+xy+9x+9y
X^2+9x+xy+9y
X(X+9)+y(X+9)
(X+9)(X+y)

2.15xy+6x+10y+4
3x(5y+2)+2(5y+2)
(5y+2)(3x+2)

3.12ab-8b-6+9a
4b(3a-2)-3(2-3a)
(3a-2)(4b-3)

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

9x^2+3xy-12x-4y
3x(3x+y)-4(3×+y)
(3x+y)(3x-4)

12x-8+3xy-2y
12x+3xy-8-2y
3x(4+y)-2(4+y)
(4+y)(3×-2)...

HOPE IT WILL HELP YOU DEAR......
