Question

plz..guys factorise this following polynomial step by step...and i will surely mark u as brainliest ​

Answer 1

1. a^2 + b^2 + 2ab + 11a + 11b - 42 ( it's 11a + 11b because thare are two minus sign , one is -11 and other is - 42 )

2. x^2 + 4y ^2 - 6x + 12y +5

hope it helps.

please mark it as brainliest answer.

Answer 2

Answer:

Step-by-step explanation:

10. (i)(a+b$)^{2}$-11 (a+b)-42

(a+b$)^{2}$-14(a+b)+3(a+b)-42

[splitting middle term method]

(a+b){a+b-14}+3{(a+b-14)} = (a+b-14)

11. (i)(x-2y)^2 -6(x-2y) +5

Let x-y =a a2 -6a+5 then do middle term
