4x2+10=48

Solution for 4x2+10=48 equation:

4x^2+10=48

We move all terms to the left:

4x^2+10-(48)=0

We add all the numbers together, and all the variables

4x^2-38=0

a = 4; b = 0; c = -38;
Δ = b2-4ac
Δ = 02-4·4·(-38)
Δ = 608
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{608}=\sqrt{16*38}=\sqrt{16}*\sqrt{38}=4\sqrt{38}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{38}}{2*4}=\frac{0-4\sqrt{38}}{8}
=-\frac{4\sqrt{38}}{8}
=-\frac{\sqrt{38}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{38}}{2*4}=\frac{0+4\sqrt{38}}{8}
=\frac{4\sqrt{38}}{8}
=\frac{\sqrt{38}}{2}
