15x^2+2=35x^2
We move all terms to the left:
15x^2+2-(35x^2)=0
We add all the numbers together, and all the variables
-20x^2+2=0
a = -20; b = 0; c = +2;
Δ = b2-4ac
Δ = 02-4·(-20)·2
Δ = 160
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{160}=\sqrt{16*10}=\sqrt{16}*\sqrt{10}=4\sqrt{10}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{10}}{2*-20}=\frac{0-4\sqrt{10}}{-40} =-\frac{4\sqrt{10}}{-40} =-\frac{\sqrt{10}}{-10} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{10}}{2*-20}=\frac{0+4\sqrt{10}}{-40} =\frac{4\sqrt{10}}{-40} =\frac{\sqrt{10}}{-10} $
