(2x+3)(x-4)=-14
We move all terms to the left:
(2x+3)(x-4)-(-14)=0
We add all the numbers together, and all the variables
(2x+3)(x-4)+14=0
We multiply parentheses ..
(+2x^2-8x+3x-12)+14=0
We get rid of parentheses
2x^2-8x+3x-12+14=0
We add all the numbers together, and all the variables
2x^2-5x+2=0
a = 2; b = -5; c = +2;
Δ = b2-4ac
Δ = -52-4·2·2
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$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-5)-3}{2*2}=\frac{2}{4} =1/2 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-5)+3}{2*2}=\frac{8}{4} =2 $
