Answer 1

Answer:

Step-by-step explanation:

12) 14xy-49$y^{2}$

    7y(2x-7y)

13) $3x^{3} - 12x^{2} y$

     $3x^{2}$(x - 4y)

14) ab +4a +3b+12

     a(b+4) +3( b+4)

(a+3)(b+4)

Answer 2

Here's ur answer dear.

The answer is absolutely right.

(12) 14xy - 49y²

7y(2x - 7y)

(13) 3x³- 12x²y

3x²(x-4y)

(14) ab+4a+3b+12

b(a+3) +4(a+3)
