Question

factorize the following​

Answer 1

Answer:

(f) = (a+1) (3a+7) and (j) = (2x+y) (x+2y)

Explanation:

(f) = 3a^2 + 4a - 7

= 3a^2 + (7-3)a - 7

= 3a^2 + 7a - 3a - 7

= a(3a+7) + 1(3a+7)

= (a+1) (3a+7)

(j) = 2x^2 + (4+1)xy + 2y^2

= 2x^2 + 4xy + xy +2y^2

= 2x(x+2y) + y(x+2y)

= (2x+y) (x+2y)
