0.04+0.4x+x^2/0.04-0.4x+x^2=49.5
We move all terms to the left:
0.04+0.4x+x^2/0.04-0.4x+x^2-(49.5)=0
We add all the numbers together, and all the variables
x^2+x^2/0.04-49.46=0
We multiply all the terms by the denominator
x^2+x^2*0.04-(49.46)*0.04=0
We add all the numbers together, and all the variables
x^2+x^2*0.04-1.9784=0
Wy multiply elements
x^2+0.04x^2-1.9784=0
We add all the numbers together, and all the variables
1.04x^2-1.9784=0
a = 1.04; b = 0; c = -1.9784;
Δ = b2-4ac
Δ = 02-4·1.04·(-1.9784)
Δ = 8.230144
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{8.230144}}{2*1.04}=\frac{0-\sqrt{8.230144}}{2.08} =-\frac{\sqrt{}}{2.08} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{8.230144}}{2*1.04}=\frac{0+\sqrt{8.230144}}{2.08} =\frac{\sqrt{}}{2.08} $
