7x^2-2.8x=48
We move all terms to the left:
7x^2-2.8x-(48)=0
a = 7; b = -2.8; c = -48;
Δ = b2-4ac
Δ = -2.82-4·7·(-48)
Δ = 1351.84
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{-(-2.8)-\sqrt{1351.84}}{2*7}=\frac{2.8-\sqrt{1351.84}}{14} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-2.8)+\sqrt{1351.84}}{2*7}=\frac{2.8+\sqrt{1351.84}}{14} $
