2x^2+0=7x+12
We move all terms to the left:
2x^2+0-(7x+12)=0
We add all the numbers together, and all the variables
2x^2-(7x+12)=0
We get rid of parentheses
2x^2-7x-12=0
a = 2; b = -7; c = -12;
Δ = b2-4ac
Δ = -72-4·2·(-12)
Δ = 145
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{-(-7)-\sqrt{145}}{2*2}=\frac{7-\sqrt{145}}{4} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-7)+\sqrt{145}}{2*2}=\frac{7+\sqrt{145}}{4} $
