7x-4=2x^2
We move all terms to the left:
7x-4-(2x^2)=0
determiningTheFunctionDomain -2x^2+7x-4=0
a = -2; b = 7; c = -4;
Δ = b2-4ac
Δ = 72-4·(-2)·(-4)
Δ = 17
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{-(7)-\sqrt{17}}{2*-2}=\frac{-7-\sqrt{17}}{-4} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(7)+\sqrt{17}}{2*-2}=\frac{-7+\sqrt{17}}{-4} $
