Question

4y (y + 7) – 3(y + 7)​

Answer 1

Step-by-step explanation:

First case,

If Factorisation then,

4y (y + 7) – 3(y + 7)​       [Taking common terms as common]

= (y+7) - (4y-3) (Ans)

Second case,

If simplification then,

4y (y + 7) – 3(y + 7)​

= 4$y^{2}$ + 21y - 3y - 21

= 4$y^{2}$ + 18 y - 21 (Ans)
