Answer
12$y^{2}$ + 4
Work Step by Step
1. Apply the distributive property.
2(12$y^{2}$ - 8y + 6) - 4(3$y^{2}$ - 4y + 2)
= 2(12$y^{2}$) + 2(-8y) + 2(6) - 4(3$y^{2}$) - 4(-4y) - 4(2)
= 24$y^{2}$ - 16y + 12 - 12$y^{2}$ + 16y - 8
2. Group like terms together.
(24$y^{2}$ - 12$y^{2}$) + (-16y + 16y) + (12 - 8)
3. Add like terms.
12$y^{2}$ + 4
