(3x^3 + 4x²) + (3x^3 – 4x^2 – 9x) =

We have to combine like terms, terms that have x raised to the same power:

First, eliminate the parenthesis:

3x^3 + 4x² + 3x^3 – 4x^2 – 9x =

We have 2 terms raised to the second power (4x^2 and -4 x^2) simply add and subtract.

3x^3+3x^3+4x^2-4x^2-9x

6x^3-9x

Answer:

(a) $9x^2+16x-4$

(b) $9a(2a+5)$

Step-by-step explanation:

(a)

$(9x-2)(x+2)=$

$9x^2-2x+18x-4=$

$9x^2+16x-4$

(b)

$18a^2+45a=$

$9a(2a+5)$

(c)

$y^2-10y+24=$

$(y-6)(y-4)$

Hope this helps!
