2(22/7)(x)=88

Solution for 2(22/7)(x)=88 equation:

2(22/7)(x)=88

We move all terms to the left:

2(22/7)(x)-(88)=0


Domain of the equation: 7)x!=0

x!=0/1

x!=0

x∈R


We add all the numbers together, and all the variables

2(+22/7)x-88=0

We multiply parentheses

44x^2-88=0

a = 44; b = 0; c = -88;
Δ = b2-4ac
Δ = 02-4·44·(-88)
Δ = 15488
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:

$\sqrt{\Delta}=\sqrt{15488}=\sqrt{7744*2}=\sqrt{7744}*\sqrt{2}=88\sqrt{2}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-88\sqrt{2}}{2*44}=\frac{0-88\sqrt{2}}{88}
=-\frac{88\sqrt{2}}{88}
=-\sqrt{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+88\sqrt{2}}{2*44}=\frac{0+88\sqrt{2}}{88}
=\frac{88\sqrt{2}}{88}
=\sqrt{2}
