170=(2w-3)w

Solution for 170=(2w-3)w equation:

170=(2w-3)w

We move all terms to the left:

170-((2w-3)w)=0


We calculate terms in parentheses: -((2w-3)w), so:

(2w-3)w

We multiply parentheses

2w^2-3w

Back to the equation:

-(2w^2-3w)


We get rid of parentheses

-2w^2+3w+170=0

a = -2; b = 3; c = +170;
Δ = b2-4ac
Δ = 32-4·(-2)·170
Δ = 1369
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1369}=37$
$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(3)-37}{2*-2}=\frac{-40}{-4}
=+10
$
$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3)+37}{2*-2}=\frac{34}{-4}
=-8+1/2
