Answer:
Step-by-step explanation:
The correct expression should be 5(3x + y)2 + 6(3x + y) - 8. It can be factorised as follows:
Let (3x + y) = z. Then, the expression becomes:
5z2 + 6z - 8
= 5z2 + 10z - 4z - 8
= 5z(z + 2) - 4(z + 2)
= (z + 2)(5z - 4)
= (3x + y + 2) [5(3x + y) - 4]
= (3x + y + 2) (15x + 5y - 4)
