F(x)=0,75x(1-0,15x)

Solution for F(x)=0,75x(1-0,15x) equation:

(F)=0.75F(1-0.15F)

We move all terms to the left:

(F)-(0.75F(1-0.15F))=0

We add all the numbers together, and all the variables

F-(0.75F(-0.15F+1))=0


We calculate terms in parentheses: -(0.75F(-0.15F+1)), so:

0.75F(-0.15F+1)

We multiply parentheses

0F^2+0F

We add all the numbers together, and all the variables

F^2+F

Back to the equation:

-(F^2+F)


We get rid of parentheses

-F^2+F-F=0

We add all the numbers together, and all the variables

-1F^2=0

a = -1; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·(-1)·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation

                              Stosujemy wzór:
$F=\frac{-b}{2a}=\frac{0}{-2}=0$
