23+3x-5x^2=3
We move all terms to the left:
23+3x-5x^2-(3)=0
We add all the numbers together, and all the variables
-5x^2+3x+20=0
a = -5; b = 3; c = +20;
Δ = b2-4ac
Δ = 32-4·(-5)·20
Δ = 409
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{-(3)-\sqrt{409}}{2*-5}=\frac{-3-\sqrt{409}}{-10} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3)+\sqrt{409}}{2*-5}=\frac{-3+\sqrt{409}}{-10} $
