4(m2)=17

Solution for 4(m2)=17 equation:

4(m2)=17

We move all terms to the left:

4(m2)-(17)=0

We add all the numbers together, and all the variables

4m^2-17=0

a = 4; b = 0; c = -17;
Δ = b2-4ac
Δ = 02-4·4·(-17)
Δ = 272
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{272}=\sqrt{16*17}=\sqrt{16}*\sqrt{17}=4\sqrt{17}$
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{17}}{2*4}=\frac{0-4\sqrt{17}}{8}
=-\frac{4\sqrt{17}}{8}
=-\frac{\sqrt{17}}{2}
$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{17}}{2*4}=\frac{0+4\sqrt{17}}{8}
=\frac{4\sqrt{17}}{8}
=\frac{\sqrt{17}}{2}
