-1.5x^2+x+4=0
a = -1.5; b = 1; c = +4;
Δ = b2-4ac
Δ = 12-4·(-1.5)·4
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$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1)-5}{2*-1.5}=\frac{-6}{-3} =+2 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+5}{2*-1.5}=\frac{4}{-3} =-1+1/3 $
