Solution for -3x^2+17x-23=-2x^2+10x-13 equation:

-3x^2+17x-23=-2x^2+10x-13

We move all terms to the left:

-3x^2+17x-23-(-2x^2+10x-13)=0

We get rid of parentheses

-3x^2+2x^2-10x+17x+13-23=0

We add all the numbers together, and all the variables

-1x^2+7x-10=0

a = -1; b = 7; c = -10;
Δ = b2-4ac
Δ = 72-4·(-1)·(-10)
Δ = 9
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{9}=3$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(7)-3}{2*-1}=\frac{-10}{-2}
=+5
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(7)+3}{2*-1}=\frac{-4}{-2}
=+2
