p^2=1.3^3

Solution for p^2=1.3^3 equation:

p^2=1.3^3

We move all terms to the left:

p^2-(1.3^3)=0

We add all the numbers together, and all the variables

p^2-2.197=0

a = 1; b = 0; c = -2.197;
Δ = b2-4ac
Δ = 02-4·1·(-2.197)
Δ = 8.788
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{8.788}}{2*1}=\frac{0-\sqrt{8.788}}{2}
=-\frac{\sqrt{}}{2}
$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{8.788}}{2*1}=\frac{0+\sqrt{8.788}}{2}
=\frac{\sqrt{}}{2}
