-2.7x^2+30x+6.5=22
We move all terms to the left:
-2.7x^2+30x+6.5-(22)=0
We add all the numbers together, and all the variables
-2.7x^2+30x-15.5=0
a = -2.7; b = 30; c = -15.5;
Δ = b2-4ac
Δ = 302-4·(-2.7)·(-15.5)
Δ = 732.6
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{-(30)-\sqrt{732.6}}{2*-2.7}=\frac{-30-\sqrt{732.6}}{-5.4} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(30)+\sqrt{732.6}}{2*-2.7}=\frac{-30+\sqrt{732.6}}{-5.4} $
