y=10x(1+0.04)x

Solution for y=10x(1+0.04)x equation:

=10Y(1+0.04)Y

We move all terms to the left:

-(10Y(1+0.04)Y)=0

We add all the numbers together, and all the variables

-(10Y(1.04)Y)=0


We calculate terms in parentheses: -(10Y(1.04)Y), so:

10Y(1.04)Y

We multiply parentheses

10.4Y^2

Back to the equation:

-(10.4Y^2)


We get rid of parentheses

-10.4Y^2=0

a = -10.4; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·(-10.4)·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation

                              Stosujemy wzór:
$Y=\frac{-b}{2a}=\frac{0}{-20.8}=0$
