16^2=(18-y)(8+y)

Solution for 16^2=(18-y)(8+y) equation:

16^2=(18-y)(8+y)

We move all terms to the left:

16^2-((18-y)(8+y))=0

We add all the numbers together, and all the variables

-((-1y+18)(y+8))+16^2=0

We add all the numbers together, and all the variables

-((-1y+18)(y+8))+256=0

We multiply parentheses ..

-((-1y^2-8y+18y+144))+256=0


We calculate terms in parentheses: -((-1y^2-8y+18y+144)), so:

(-1y^2-8y+18y+144)

We get rid of parentheses

-1y^2-8y+18y+144

We add all the numbers together, and all the variables

-1y^2+10y+144

Back to the equation:

-(-1y^2+10y+144)


We get rid of parentheses

1y^2-10y-144+256=0

We add all the numbers together, and all the variables

y^2-10y+112=0

a = 1; b = -10; c = +112;
Δ = b2-4ac
Δ = -102-4·1·112
Δ = -348
Delta is less than zero, so there is no solution for the equation
