x=3*(x+5)*(x+7)

Solution for x=3*(x+5)*(x+7) equation:

x=3(x+5)(x+7)

We move all terms to the left:

x-(3(x+5)(x+7))=0

We multiply parentheses ..

-(3(+x^2+7x+5x+35))+x=0


We calculate terms in parentheses: -(3(+x^2+7x+5x+35)), so:

3(+x^2+7x+5x+35)

We multiply parentheses

3x^2+21x+15x+105

We add all the numbers together, and all the variables

3x^2+36x+105

Back to the equation:

-(3x^2+36x+105)


We add all the numbers together, and all the variables

x-(3x^2+36x+105)=0

We get rid of parentheses

-3x^2+x-36x-105=0

We add all the numbers together, and all the variables

-3x^2-35x-105=0

a = -3; b = -35; c = -105;
Δ = b2-4ac
Δ = -352-4·(-3)·(-105)
Δ = -35
Delta is less than zero, so there is no solution for the equation
