4b^2-354=0

Solution for 4b^2-354=0 equation:

4b^2-354=0

a = 4; b = 0; c = -354;
Δ = b2-4ac
Δ = 02-4·4·(-354)
Δ = 5664
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$b_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$b_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{5664}=\sqrt{16*354}=\sqrt{16}*\sqrt{354}=4\sqrt{354}$
$b_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{354}}{2*4}=\frac{0-4\sqrt{354}}{8}
=-\frac{4\sqrt{354}}{8}
=-\frac{\sqrt{354}}{2}
$
$b_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{354}}{2*4}=\frac{0+4\sqrt{354}}{8}
=\frac{4\sqrt{354}}{8}
=\frac{\sqrt{354}}{2}
