144x^2=121

Solution for 144x^2=121 equation:

144x^2=121

We move all terms to the left:

144x^2-(121)=0

a = 144; b = 0; c = -121;
Δ = b2-4ac
Δ = 02-4·144·(-121)
Δ = 69696
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{69696}=264$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-264}{2*144}=\frac{-264}{288}
=-11/12
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+264}{2*144}=\frac{264}{288}
=11/12
