Solution for (1/4)a=31 equation:



(1/4)a=31
We move all terms to the left:
(1/4)a-(31)=0
Domain of the equation: 4)a!=0
a!=0/1
a!=0
a∈R
We add all the numbers together, and all the variables
(+1/4)a-31=0
We multiply parentheses
a^2-31=0
a = 1; b = 0; c = -31;
Δ = b2-4ac
Δ = 02-4·1·(-31)
Δ = 124
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:
$\sqrt{\Delta}=\sqrt{124}=\sqrt{4*31}=\sqrt{4}*\sqrt{31}=2\sqrt{31}$
$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-2\sqrt{31}}{2*1}=\frac{0-2\sqrt{31}}{2} =-\frac{2\sqrt{31}}{2} =-\sqrt{31} $
$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+2\sqrt{31}}{2*1}=\frac{0+2\sqrt{31}}{2} =\frac{2\sqrt{31}}{2} =\sqrt{31} $
