0.35=35x2

Solution for 0.35=35x2 equation:

0.35=35x^2

We move all terms to the left:

0.35-(35x^2)=0

a = -35; b = 0; c = +0.35;
Δ = b2-4ac
Δ = 02-4·(-35)·0.35
Δ = 49
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{49}=7$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-7}{2*-35}=\frac{-7}{-70}
=1/10
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+7}{2*-35}=\frac{7}{-70}
=-1/10
