Question

plz...solve this factorise.and i will surely mark u as brainliest ​

Answer 1

Step-by-step explanation:

7. 5ph - 10qk + 2rph - 4qrk

5ph+2rph-10qk-4qrk

ph(5+2r) - 2qk(5+2r)

(5+2r) (ph-2qk)

8. ab(x²+y²)-xy(a²+b²)

abx²+aby²-xya²-xyb²

abx²-a²xy+aby²-b²xy

ax(bx-ay)+by(ay-bx)

ax(bx-ay)-by(bx-ay)

(bx-ay) (ax-by)

9. a³+ab(1-2a)-2b²

a³+ab-2a²b-2b²

a(a²+b)-2b(a²+b)

(a²+b) (a-2b)

I hope this will help you
