1/2x+4(x-1)=23
We move all terms to the left:
1/2x+4(x-1)-(23)=0
Domain of the equation: 2x!=0We multiply parentheses
x!=0/2
x!=0
x∈R
1/2x+4x-4-23=0
We multiply all the terms by the denominator
4x*2x-4*2x-23*2x+1=0
Wy multiply elements
8x^2-8x-46x+1=0
We add all the numbers together, and all the variables
8x^2-54x+1=0
a = 8; b = -54; c = +1;
Δ = b2-4ac
Δ = -542-4·8·1
Δ = 2884
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{2884}=\sqrt{4*721}=\sqrt{4}*\sqrt{721}=2\sqrt{721}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-54)-2\sqrt{721}}{2*8}=\frac{54-2\sqrt{721}}{16} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-54)+2\sqrt{721}}{2*8}=\frac{54+2\sqrt{721}}{16} $
