2x^2+10=134

Solution for 2x^2+10=134 equation:

2x^2+10=134

We move all terms to the left:

2x^2+10-(134)=0

We add all the numbers together, and all the variables

2x^2-124=0

a = 2; b = 0; c = -124;
Δ = b2-4ac
Δ = 02-4·2·(-124)
Δ = 992
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:

$\sqrt{\Delta}=\sqrt{992}=\sqrt{16*62}=\sqrt{16}*\sqrt{62}=4\sqrt{62}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{62}}{2*2}=\frac{0-4\sqrt{62}}{4}
=-\frac{4\sqrt{62}}{4}
=-\sqrt{62}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{62}}{2*2}=\frac{0+4\sqrt{62}}{4}
=\frac{4\sqrt{62}}{4}
=\sqrt{62}
