7p^2-34-5=0

Solution for 7p^2-34-5=0 equation:

7p^2-34-5=0

We add all the numbers together, and all the variables

7p^2-39=0

a = 7; b = 0; c = -39;
Δ = b2-4ac
Δ = 02-4·7·(-39)
Δ = 1092
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{1092}=\sqrt{4*273}=\sqrt{4}*\sqrt{273}=2\sqrt{273}$
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-2\sqrt{273}}{2*7}=\frac{0-2\sqrt{273}}{14}
=-\frac{2\sqrt{273}}{14}
=-\frac{\sqrt{273}}{7}
$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+2\sqrt{273}}{2*7}=\frac{0+2\sqrt{273}}{14}
=\frac{2\sqrt{273}}{14}
=\frac{\sqrt{273}}{7}
