40=(w)(w+6)
We move all terms to the left:
40-((w)(w+6))=0
We calculate terms in parentheses: -(w(w+6)), so:We get rid of parentheses
w(w+6)
We multiply parentheses
w^2+6w
Back to the equation:
-(w^2+6w)
-w^2-6w+40=0
We add all the numbers together, and all the variables
-1w^2-6w+40=0
a = -1; b = -6; c = +40;
Δ = b2-4ac
Δ = -62-4·(-1)·40
Δ = 196
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{196}=14$$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-6)-14}{2*-1}=\frac{-8}{-2} =+4 $$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-6)+14}{2*-1}=\frac{20}{-2} =-10 $
