Exercise 31 Page 25

Apply the Distributive Property.

2m^3+5m^2-4

Practice makes perfect

To simplify the expression, we will first add the trinomials. Then we will apply the Distributive Property.

(m+2)[ (m^2+3m-6)+(m^2-2m+4) ]

Remove parentheses

(m+2)( m^2+3m-6+m^2-2m+4 )

Add and subtract terms

(m+2)( 2m^2+m-2 )

Distribute ( 2m^2+m-2 )

m( 2m^2+m-2 )+2( 2m^2+m-2 )

Distribute m

2m^3+m^2-2m+2( 2m^2+m-2 )

Distribute 2

2m^3+m^2-2m+4m^2+2m-4

Add terms

2m^3+5m^2-4
