x*2x=1800
We move all terms to the left:
x*2x-(1800)=0
Wy multiply elements
2x^2-1800=0
a = 2; b = 0; c = -1800;
Δ = b2-4ac
Δ = 02-4·2·(-1800)
Δ = 14400
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{14400}=120$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-120}{2*2}=\frac{-120}{4} =-30 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+120}{2*2}=\frac{120}{4} =30 $
