Wy multiply elements

2X^2-300X+3=0

a = 2; b = -300; c = +3;
Δ = b2-4ac
Δ = -3002-4·2·3
Δ = 89976
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:

$\sqrt{\Delta}=\sqrt{89976}=\sqrt{4*22494}=\sqrt{4}*\sqrt{22494}=2\sqrt{22494}$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-300)-2\sqrt{22494}}{2*2}=\frac{300-2\sqrt{22494}}{4}
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-300)+2\sqrt{22494}}{2*2}=\frac{300+2\sqrt{22494}}{4}
