(X+7)(2x+8)=(x+17)(x)

Solution for (X+7)(2x+8)=(x+17)(x) equation:

(X+7)(2X+8)=(X+17)(X)

We move all terms to the left:

(X+7)(2X+8)-((X+17)(X))=0

We multiply parentheses ..

(+2X^2+8X+14X+56)-((X+17)X)=0


We calculate terms in parentheses: -((X+17)X), so:

(X+17)X

We multiply parentheses

X^2+17X

Back to the equation:

-(X^2+17X)


We get rid of parentheses

2X^2-X^2+8X+14X-17X+56=0

We add all the numbers together, and all the variables

X^2+5X+56=0

a = 1; b = 5; c = +56;
Δ = b2-4ac
Δ = 52-4·1·56
Δ = -199
Delta is less than zero, so there is no solution for the equation
