75=x+(x^2/20)

Solution for 75=x+(x^2/20) equation:

75=x+(x^2/20)

We move all terms to the left:

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

We multiply all the terms by the denominator


-(x+(x^2+75*20))=0


We calculate terms in parentheses: -(x+(x^2+75*20)), so:

x+(x^2+75*20)

We get rid of parentheses

x^2+x+75*20

We add all the numbers together, and all the variables

x^2+x+1500

Back to the equation:

-(x^2+x+1500)


We get rid of parentheses

-x^2-x-1500=0

We add all the numbers together, and all the variables

-1x^2-1x-1500=0

a = -1; b = -1; c = -1500;
Δ = b2-4ac
Δ = -12-4·(-1)·(-1500)
Δ = -5999
Delta is less than zero, so there is no solution for the equation
