-4y+8=4(2y-2)-2(16+8y)y+8=4(2y-2)-2(-16+8y)

Solution for -4y+8=4(2y-2)-2(16+8y)y+8=4(2y-2)-2(-16+8y) equation:

-4y+8=4(2y-2)-2(16+8y)y+8=4(2y-2)-2(-16+8y)

We move all terms to the left:

-4y+8-(4(2y-2)-2(16+8y)y+8)=0

We add all the numbers together, and all the variables

-4y-(4(2y-2)-2(8y+16)y+8)+8=0


We calculate terms in parentheses: -(4(2y-2)-2(8y+16)y+8), so:

4(2y-2)-2(8y+16)y+8

We multiply parentheses

-16y^2+8y-32y-8+8

We add all the numbers together, and all the variables

-16y^2-24y

Back to the equation:

-(-16y^2-24y)


We get rid of parentheses

16y^2+24y-4y+8=0

We add all the numbers together, and all the variables

16y^2+20y+8=0

a = 16; b = 20; c = +8;
Δ = b2-4ac
Δ = 202-4·16·8
Δ = -112
Delta is less than zero, so there is no solution for the equation
