(6-u)(3u+7)=0
We add all the numbers together, and all the variables
(-1u+6)(3u+7)=0
We multiply parentheses ..
(-3u^2-7u+18u+42)=0
We get rid of parentheses
-3u^2-7u+18u+42=0
We add all the numbers together, and all the variables
-3u^2+11u+42=0
a = -3; b = 11; c = +42;
Δ = b2-4ac
Δ = 112-4·(-3)·42
Δ = 625
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$u_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$u_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{625}=25$$u_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(11)-25}{2*-3}=\frac{-36}{-6} =+6 $$u_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(11)+25}{2*-3}=\frac{14}{-6} =-2+1/3 $
