2x+3x^2-7x+8x^2=0
We add all the numbers together, and all the variables
11x^2-5x=0
a = 11; b = -5; c = 0;
Δ = b2-4ac
Δ = -52-4·11·0
Δ = 25
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{25}=5$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-5)-5}{2*11}=\frac{0}{22} =0 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-5)+5}{2*11}=\frac{10}{22} =5/11 $
