(x-5)2=x2-7(x-7)

Solution for (x-5)2=x2-7(x-7) equation:

(x-5)2=x2-7(x-7)

We move all terms to the left:

(x-5)2-(x2-7(x-7))=0

We multiply parentheses

2x-(x2-7(x-7))-10=0


We calculate terms in parentheses: -(x2-7(x-7)), so:

x2-7(x-7)

We add all the numbers together, and all the variables

x^2-7(x-7)

We multiply parentheses

x^2-7x+49

Back to the equation:

-(x^2-7x+49)


We get rid of parentheses

-x^2+2x+7x-49-10=0

We add all the numbers together, and all the variables

-1x^2+9x-59=0

a = -1; b = 9; c = -59;
Δ = b2-4ac
Δ = 92-4·(-1)·(-59)
Δ = -155
Delta is less than zero, so there is no solution for the equation
