25m*25m-16=0

Solution for 25m*25m-16=0 equation:

25m*25m-16=0

Wy multiply elements

625m^2-16=0

a = 625; b = 0; c = -16;
Δ = b2-4ac
Δ = 02-4·625·(-16)
Δ = 40000
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{40000}=200$
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-200}{2*625}=\frac{-200}{1250}
=-4/25
$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+200}{2*625}=\frac{200}{1250}
=4/25
