(x-2)(4x-3)=84
We move all terms to the left:
(x-2)(4x-3)-(84)=0
We multiply parentheses ..
(+4x^2-3x-8x+6)-84=0
We get rid of parentheses
4x^2-3x-8x+6-84=0
We add all the numbers together, and all the variables
4x^2-11x-78=0
a = 4; b = -11; c = -78;
Δ = b2-4ac
Δ = -112-4·4·(-78)
Δ = 1369
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{1369}=37$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-11)-37}{2*4}=\frac{-26}{8} =-3+1/4 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-11)+37}{2*4}=\frac{48}{8} =6 $
