For this case we have the following expression:

(3x + 8) (3x-3)

We apply distributive property, which by definition establishes that:

(a + b) (c + d) = ac + ad + bc + bd

So:

(3x + 8) (3x-3) =\\9x ^ 2-9x + 24x-24 =\\9x ^ 2 + 15x-24

Answer:

9x ^ 2 + 15x-24

This is what I've done so far but does anyone know what I do next or did I make a mistake
grigory [225]
Remmeber, you can do anything to an equation as long as you do it to both sides

for inequalities, if you multiply or divide both sides by a negive, flip the direction of the inequality sign

pemdas always applies
but also the commutative property and assiociative property

so
2(5y+13)-6<20
add 6 both sides
2(5y+13)<26
divide both sides by 2 (easier that distributing)
5y+13<13
minus 13 both sides
5y<0
y<0 is the solution
