1.3x2+4x2=35

Solution for 1.3x2+4x2=35 equation:

1.3x^2+4x^2=35

We move all terms to the left:

1.3x^2+4x^2-(35)=0

We add all the numbers together, and all the variables

5.3x^2-35=0

a = 5.3; b = 0; c = -35;
Δ = b2-4ac
Δ = 02-4·5.3·(-35)
Δ = 742
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{742}}{2*5.3}=\frac{0-\sqrt{742}}{10.6}
=-\frac{\sqrt{}}{10.6}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{742}}{2*5.3}=\frac{0+\sqrt{742}}{10.6}
=\frac{\sqrt{}}{10.6}
