Question

3-5a-5b-12(a+b)²
factorise it​

Answer 1

Answer:

3−5a−5b−12(a+b)²

Above terms can be written as,

3−5(a+b)−12(a+b)²

3−9(a+b)+4( a+b)−12(a+b)²

Take out common in all terms we get,

3(1−3(a+b))+4(a+b)(1−3(a+b))

(1−3(a+b))(3+4(a+b))

(1−3a−3b)(3+4a+4b)

Answer 2

Answer:

(1-3a-3b) (3+4a+4b) is your answer dear
