Y=(x-14)(x-14)

Solution for Y=(x-14)(x-14) equation:

=(Y-14)(Y-14)

We move all terms to the left:

-((Y-14)(Y-14))=0

We multiply parentheses ..

-((+Y^2-14Y-14Y+196))=0


We calculate terms in parentheses: -((+Y^2-14Y-14Y+196)), so:

(+Y^2-14Y-14Y+196)

We get rid of parentheses

Y^2-14Y-14Y+196

We add all the numbers together, and all the variables

Y^2-28Y+196

Back to the equation:

-(Y^2-28Y+196)


We get rid of parentheses

-Y^2+28Y-196=0

We add all the numbers together, and all the variables

-1Y^2+28Y-196=0

a = -1; b = 28; c = -196;
Δ = b2-4ac
Δ = 282-4·(-1)·(-196)
Δ = 0
Delta is equal to zero, so there is only one solution to the equation

                              Stosujemy wzór:
$Y=\frac{-b}{2a}=\frac{-28}{-2}=+14$
