You must simplify this by removing brackets

and then solve the equation.

This may help you.

Answer 2

Step-by-step explanation:

1) (y-8) (3y-4)

y (3y-4) -8 (3y -4)

3y^2 - 4y -24y + 32

3y ^2 - 28y +32

2) ( 2.5 l - 0.5m ) ( 0.2 l + 0.5m)

2.5 ( 0.2 l + 0.5m) - 0.5m ( 0.2 l + 0.5m)

50 l^2 + 1.25ml - 10ml - 25m^2

50 l^2 + 11.25 ml - 25 m^2

3) ( a +3b) ( n+5)

a(n+5) +3b (n+5)

an + 5a +3b+ 3nb + 15b

an + 5a + 18b + 3nb

4) ( 2pq + 3q^2) ( 3pq - 2q^2 )

6p^2q^2 - 4pq^3 + 3pq^3 -6q^4

6p^2q^2 -pq^3 -6q4
