70-180=x(x-20)=

Solution for 70-180=x(x-20)= equation:

70-180=x(x-20)=

We move all terms to the left:

70-180-(x(x-20))=0

We add all the numbers together, and all the variables

-(x(x-20))-110=0


We calculate terms in parentheses: -(x(x-20)), so:

x(x-20)

We multiply parentheses

x^2-20x

Back to the equation:

-(x^2-20x)


We get rid of parentheses

-x^2+20x-110=0

We add all the numbers together, and all the variables

-1x^2+20x-110=0

a = -1; b = 20; c = -110;
Δ = b2-4ac
Δ = 202-4·(-1)·(-110)
Δ = -40
Delta is less than zero, so there is no solution for the equation
