.(0.15)(x)=0.04

Solution for .(0.15)(x)=0.04 equation:

.(0.15)(x)=0.04

We move all terms to the left:

.(0.15)(x)-(0.04)=0

We add all the numbers together, and all the variables

.(0.15)x-0.04=0

We multiply parentheses

0.15x^2-0.04=0

a = 0.15; b = 0; c = -0.04;
Δ = b2-4ac
Δ = 02-4·0.15·(-0.04)
Δ = 0.024
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{0.024}}{2*0.15}=\frac{0-\sqrt{0.024}}{0.3}
=-\frac{\sqrt{}}{0.3}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{0.024}}{2*0.15}=\frac{0+\sqrt{0.024}}{0.3}
=\frac{\sqrt{}}{0.3}
