Question

7 + 10(a+b)- 8(a+b)^2 factorize this​

Answer 1

Answer:

7+10(a+b)-8(a^2+b^2+2ab)

7+10a+10b-8a^2-8b^2-16ab

Answer 2

Step-by-step explanation:

-8(a+b)^2+10(a+b)+7

=8(a+b)^2-10(a+b)-7. (take minus as common)

=8(a+b)^2-14(a+b)+4(a+b)-7

=2(a+b){4(a+b)-7}+1{4(a+b)-7}

={2(a+b)+1}{4(a+b)-7}
