4^3.3=7x^2

Solution for 4^3.3=7x^2 equation:

4^3.3=7x^2

We move all terms to the left:

4^3.3-(7x^2)=0

We add all the numbers together, and all the variables

-7x^2+97.005860256665=0

a = -7; b = 0; c = +97.005860256665;
Δ = b2-4ac
Δ = 02-4·(-7)·97.005860256665
Δ = 2716.1640871866
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{2716.1640871866}}{2*-7}=\frac{0-\sqrt{2716.1640871866}}{-14}
=-\frac{\sqrt{}}{-14}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{2716.1640871866}}{2*-7}=\frac{0+\sqrt{2716.1640871866}}{-14}
=\frac{\sqrt{}}{-14}
