2w^2-3=44

Solution for 2w^2-3=44 equation:

2w^2-3=44

We move all terms to the left:

2w^2-3-(44)=0

We add all the numbers together, and all the variables

2w^2-47=0

a = 2; b = 0; c = -47;
Δ = b2-4ac
Δ = 02-4·2·(-47)
Δ = 376
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{376}=\sqrt{4*94}=\sqrt{4}*\sqrt{94}=2\sqrt{94}$
$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-2\sqrt{94}}{2*2}=\frac{0-2\sqrt{94}}{4}
=-\frac{2\sqrt{94}}{4}
=-\frac{\sqrt{94}}{2}
$
$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+2\sqrt{94}}{2*2}=\frac{0+2\sqrt{94}}{4}
=\frac{2\sqrt{94}}{4}
=\frac{\sqrt{94}}{2}
