Y=x(x-8)+2(4x+15)

Solution for Y=x(x-8)+2(4x+15) equation:

=Y(Y-8)+2(4Y+15)

We move all terms to the left:

-(Y(Y-8)+2(4Y+15))=0


We calculate terms in parentheses: -(Y(Y-8)+2(4Y+15)), so:

Y(Y-8)+2(4Y+15)

We multiply parentheses

Y^2-8Y+8Y+30

We add all the numbers together, and all the variables

Y^2+30

Back to the equation:

-(Y^2+30)


We get rid of parentheses

-Y^2-30=0

We add all the numbers together, and all the variables

-1Y^2-30=0

a = -1; b = 0; c = -30;
Δ = b2-4ac
Δ = 02-4·(-1)·(-30)
Δ = -120
Delta is less than zero, so there is no solution for the equation
