196x^2=4

Solution for 196x^2=4 equation:

196x^2=4

We move all terms to the left:

196x^2-(4)=0

a = 196; b = 0; c = -4;
Δ = b2-4ac
Δ = 02-4·196·(-4)
Δ = 3136
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{3136}=56$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-56}{2*196}=\frac{-56}{392}
=-1/7
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+56}{2*196}=\frac{56}{392}
=1/7
