15m*11m=165m

Solution for 15m*11m=165m equation:

15m*11m=165m

We move all terms to the left:

15m*11m-(165m)=0

We add all the numbers together, and all the variables

-165m+15m*11m=0

Wy multiply elements

165m^2-165m=0

a = 165; b = -165; c = 0;
Δ = b2-4ac
Δ = -1652-4·165·0
Δ = 27225
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{27225}=165$
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-165)-165}{2*165}=\frac{0}{330}
=0
$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-165)+165}{2*165}=\frac{330}{330}
=1
