(4x-1)(9x+6)=0
We multiply parentheses ..
(+36x^2+24x-9x-6)=0
We get rid of parentheses
36x^2+24x-9x-6=0
We add all the numbers together, and all the variables
36x^2+15x-6=0
a = 36; b = 15; c = -6;
Δ = b2-4ac
Δ = 152-4·36·(-6)
Δ = 1089
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{1089}=33$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(15)-33}{2*36}=\frac{-48}{72} =-2/3 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(15)+33}{2*36}=\frac{18}{72} =1/4 $
