3x2+4x-2=x2-5x+3

Solution for 3x2+4x-2=x2-5x+3 equation:

3x^2+4x-2=x2-5x+3

We move all terms to the left:

3x^2+4x-2-(x2-5x+3)=0

We add all the numbers together, and all the variables

3x^2-(+x^2-5x+3)+4x-2=0

We get rid of parentheses

3x^2-x^2+5x+4x-3-2=0

We add all the numbers together, and all the variables

2x^2+9x-5=0

a = 2; b = 9; c = -5;
Δ = b2-4ac
Δ = 92-4·2·(-5)
Δ = 121
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{121}=11$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(9)-11}{2*2}=\frac{-20}{4}
=-5
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(9)+11}{2*2}=\frac{2}{4}
=1/2
