Please help with this "Q".

To simplify the expression 16(a+b)^2 - 4a - 4b, we can expand the square term and then combine like terms:

16(a+b)^2 - 4a - 4b

Expanding the square term: = 16(a^2 + 2ab + b^2) - 4a - 4b

Distributing 16: = 16a^2 + 32ab + 16b^2 - 4a - 4b

Combining like terms: = 16a^2 - 4a + 32ab - 4b + 16b^2

The simplified form of the expression is 16a^2 - 4a + 32ab - 4b + 16b^2.

I hope this help you remember - b^2 is b square. You can also take help fromOnline learning site
