Which of the following equations are true? Select three that apply. A (2x−1) (x2+4x+3)= 2x3+7x2+2x−3
B (4x2−3x+6)+(5x2−8)=9x2−3x−2
C (8x−4x2)+(2x2−5x)=−2x4+3x
D (4x2+4x−5)−(6x2−5x−3)=−2x2−x−8
E (3x3−5+2x)−(5x−6+x3)=2x3−3x+1

______________________________

Use the distributive property to multiply by and combine like terms:

- So this is True.

Combine like terms and subtract 8 from 6 to get −2:

- So this is True.

Combine like terms:

- So this is False.

Combine like terms and add -5 and 3 to get -2:

- So this is False.

Combine like terms and add -5 and 6 to get 1:

- So this is True.
