Y=-0.28(x-3.2)(x-0.7)

Solution for Y=-0.28(x-3.2)(x-0.7) equation:

=-0.28(Y-3.2)(Y-0.7)

We move all terms to the left:

-(-0.28(Y-3.2)(Y-0.7))=0

We multiply parentheses ..

-(-0.28(+Y^2-0.7Y-3.2Y+2.24))=0


We calculate terms in parentheses: -(-0.28(+Y^2-0.7Y-3.2Y+2.24)), so:

-0.28(+Y^2-0.7Y-3.2Y+2.24)

We multiply parentheses

-0.28Y^2-0Y+0.84Y-0.6272

We add all the numbers together, and all the variables

-0.28Y^2-0.16Y-0.6272

Back to the equation:

-(-0.28Y^2-0.16Y-0.6272)


We get rid of parentheses

0.28Y^2+0.16Y+0.6272=0

a = 0.28; b = 0.16; c = +0.6272;
Δ = b2-4ac
Δ = 0.162-4·0.28·0.6272
Δ = -0.676864
Delta is less than zero, so there is no solution for the equation
