2X(3-5y)=0

Solution for 2X(3-5y)=0 equation:

2X(3-5X)=0

We add all the numbers together, and all the variables

2X(-5X+3)=0

We multiply parentheses

-10X^2+6X=0

a = -10; b = 6; c = 0;
Δ = b2-4ac
Δ = 62-4·(-10)·0
Δ = 36
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{36}=6$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(6)-6}{2*-10}=\frac{-12}{-20}
=3/5
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(6)+6}{2*-10}=\frac{0}{-20}
=0
