2x^2+3x+2=14

Solution for 2x^2+3x+2=14 equation:

2x^2+3x+2=14

We move all terms to the left:

2x^2+3x+2-(14)=0

We add all the numbers together, and all the variables

2x^2+3x-12=0

a = 2; b = 3; c = -12;
Δ = b2-4ac
Δ = 32-4·2·(-12)
Δ = 105
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{105}}{2*2}=\frac{-3-\sqrt{105}}{4}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3)+\sqrt{105}}{2*2}=\frac{-3+\sqrt{105}}{4}
