120=x+((x^2)/20)

Solution for 120=x+((x^2)/20) equation:

120=x+((x^2)/20)

We move all terms to the left:

120-(x+((x^2)/20))=0

We multiply all the terms by the denominator


-(x+(x^2+120*20))=0


We calculate terms in parentheses: -(x+(x^2+120*20)), so:

x+(x^2+120*20)

We get rid of parentheses

x^2+x+120*20

We add all the numbers together, and all the variables

x^2+x+2400

Back to the equation:

-(x^2+x+2400)


We get rid of parentheses

-x^2-x-2400=0

We add all the numbers together, and all the variables

-1x^2-1x-2400=0

a = -1; b = -1; c = -2400;
Δ = b2-4ac
Δ = -12-4·(-1)·(-2400)
Δ = -9599
Delta is less than zero, so there is no solution for the equation
