Question

3. Factorise the following.
(i) 2ab + 2dc + 2ac + 2bd
(ii) px - qy - qx + py
(iii) x2 – 2y + x - 2xy
(iv) 6a2 - 12b + 8a-9ab
(v) 6xy + 3 – 2y - 9x
(vi) 8yz - 3x + 6xz - 4y
(vii) 6a2 + 6ab-6a - 6b
(viii) 6xy - 5 + 3x - 10y
(ix) 24y2 + 12x – 24y - 12xy
(x) 1583 - 20 - 30x + 10x2​

Answer 1

Answer:

1 -2a(b+c)+2d(b+c)

=(b+c)(2a+2d)

2- px+qx+py+qy=0

=x(p+q)+y(p+q)=o

=(p+q) (x+y) = 0

3 mujhe nahi aata sorry

4 2a(3a+4)-3b(3a+4)

=(3a+4) (2a-3b)

5=6xy-9x+3-2y

=3x(2y-3)+3-2y

6 mujhe nahi aata

7 mujhe nahi aata

8 bhi nahi aata

9 bhi nahi aata

10 Bhi nahi aata

hope you understand

sorry for the unsolved answer
