(3a + 4b)^2 - 10b
Expanding the square of the binomial using the formula (a + b)^2 = a^2 + 2ab + b^2, we get:
(3a)^2 + 2(3a)(4b) + (4b)^2 - 10b= 9a^2 + 24ab + 16b^2 - 10b
Therefore, the expression simplifies to:
9a^2 + 24ab + 16b^2 - 10b
(3a + 4b)^2 - 10b
Expanding the square of the binomial using the formula (a + b)^2 = a^2 + 2ab + b^2, we get:
(3a)^2 + 2(3a)(4b) + (4b)^2 - 10b
= 9a^2 + 24ab + 16b^2 - 10b
Therefore, the expression simplifies to:
9a^2 + 24ab + 16b^2 - 10b
