(3.1x-6.2)(0.5x+1)=0
We multiply parentheses ..
(+0x^2+3x-0x-6.2)=0
We get rid of parentheses
0x^2+3x-0x-6.2=0
We add all the numbers together, and all the variables
x^2+2x-6.2=0
a = 1; b = 2; c = -6.2;
Δ = b2-4ac
Δ = 22-4·1·(-6.2)
Δ = 28.8
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{-(2)-\sqrt{28.8}}{2*1}=\frac{-2-\sqrt{28.8}}{2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2)+\sqrt{28.8}}{2*1}=\frac{-2+\sqrt{28.8}}{2} $
