(14+y)(14-y)=(14+y)(14-y)

Solution for (14+y)(14-y)=(14+y)(14-y) equation:

(14+y)(14-y)=(14+y)(14-y)

We move all terms to the left:

(14+y)(14-y)-((14+y)(14-y))=0

We add all the numbers together, and all the variables

(y+14)(-1y+14)-((y+14)(-1y+14))=0

We multiply parentheses ..

(-1y^2+14y-14y+196)-((-1y^2+14y-14y+196))=0


We calculate terms in parentheses: -((-1y^2+14y-14y+196)), so:

(-1y^2+14y-14y+196)

We get rid of parentheses

-1y^2+14y-14y+196

We add all the numbers together, and all the variables

-1y^2+196

Back to the equation:

-(-1y^2+196)


We get rid of parentheses

-1y^2+1y^2+14y-14y+196-196=0

We add all the numbers together, and all the variables

=0

y=0/1

y=0
