Question

Subtract and simplify.
(-y2 – 4y - 8) – (-4y2 – 6y + 3)

Answer 1

3y^2+2y-11

Explanation:

I am guessing for -y2 and -4y2 you meant exponents; it would still get you the same answer though.

-y^2-4y-8 - (-4y2-6y+3)

1.Distribute; -y^2-4y-8 -1(-4y2*-1-6y*-1+3*-1)

you then get; -y^2+(-4y)+(-8) +4y^2+6y+-3

2.Combine like terms; 3y^2+2y-11

Then you get: 3y^2+2y-11.

Answer 2

3y^2 +2y -11

Explanation:

(-y^2 – 4y - 8) – (-4y^2 – 6y + 3)

Distribute the minus sign

(-y^2 – 4y - 8) +4y^2 + 6y - 3

Combine like terms

-y^2+4y^2 – 4y + 6y - 3-8

3y^2 +2y -11
