15=x(x+4)1/2

Solution for 15=x(x+4)1/2 equation:

15=x(x+4)1/2

We move all terms to the left:

15-(x(x+4)1/2)=0

We multiply all the terms by the denominator


-(x(x+4)1+15*2)=0


We calculate terms in parentheses: -(x(x+4)1+15*2), so:

x(x+4)1+15*2

We add all the numbers together, and all the variables

x(x+4)1+30

We multiply parentheses

x^2+4x+30

Back to the equation:

-(x^2+4x+30)


We get rid of parentheses

-x^2-4x-30=0

We add all the numbers together, and all the variables

-1x^2-4x-30=0

a = -1; b = -4; c = -30;
Δ = b2-4ac
Δ = -42-4·(-1)·(-30)
Δ = -104
Delta is less than zero, so there is no solution for the equation
