1/2*4x*5x=40
We move all terms to the left:
1/2*4x*5x-(40)=0
Domain of the equation: 2*4x*5x!=0We multiply all the terms by the denominator
x!=0/1
x!=0
x∈R
-40*2*4x*5x+1=0
Wy multiply elements
-1600x^2*4+1=0
Wy multiply elements
-6400x^2+1=0
a = -6400; b = 0; c = +1;
Δ = b2-4ac
Δ = 02-4·(-6400)·1
Δ = 25600
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{25600}=160$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-160}{2*-6400}=\frac{-160}{-12800} =1/80 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+160}{2*-6400}=\frac{160}{-12800} =-1/80 $
