(1/2)4x=180

Solution for (1/2)4x=180 equation:

(1/2)4x=180

We move all terms to the left:

(1/2)4x-(180)=0


Domain of the equation: 2)4x!=0

x!=0/1

x!=0

x∈R


We add all the numbers together, and all the variables

(+1/2)4x-180=0

We multiply parentheses

4x^2-180=0

a = 4; b = 0; c = -180;
Δ = b2-4ac
Δ = 02-4·4·(-180)
Δ = 2880
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:

$\sqrt{\Delta}=\sqrt{2880}=\sqrt{576*5}=\sqrt{576}*\sqrt{5}=24\sqrt{5}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-24\sqrt{5}}{2*4}=\frac{0-24\sqrt{5}}{8}
=-\frac{24\sqrt{5}}{8}
=-3\sqrt{5}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+24\sqrt{5}}{2*4}=\frac{0+24\sqrt{5}}{8}
=\frac{24\sqrt{5}}{8}
=3\sqrt{5}
