5m*7m=875

Solution for 5m*7m=875 equation:

5m*7m=875

We move all terms to the left:

5m*7m-(875)=0

Wy multiply elements

35m^2-875=0

a = 35; b = 0; c = -875;
Δ = b2-4ac
Δ = 02-4·35·(-875)
Δ = 122500
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{122500}=350$
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-350}{2*35}=\frac{-350}{70}
=-5
$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+350}{2*35}=\frac{350}{70}
=5
