15x(2)-11x+2=0

Solution for 15x(2)-11x+2=0 equation:

15x(2)-11x+2=0

We add all the numbers together, and all the variables

15x^2-11x+2=0

a = 15; b = -11; c = +2;
Δ = b2-4ac
Δ = -112-4·15·2
Δ = 1
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1}=1$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-11)-1}{2*15}=\frac{10}{30}
=1/3
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-11)+1}{2*15}=\frac{12}{30}
=2/5
