1/2x-16=28-1/4x
We move all terms to the left:
1/2x-16-(28-1/4x)=0
Domain of the equation: 2x!=0
x!=0/2
x!=0
x∈R
Domain of the equation: 4x)!=0We add all the numbers together, and all the variables
x!=0/1
x!=0
x∈R
1/2x-(-1/4x+28)-16=0
We get rid of parentheses
1/2x+1/4x-28-16=0
We calculate fractions
4x/8x^2+2x/8x^2-28-16=0
We add all the numbers together, and all the variables
4x/8x^2+2x/8x^2-44=0
We multiply all the terms by the denominator
4x+2x-44*8x^2=0
We add all the numbers together, and all the variables
6x-44*8x^2=0
Wy multiply elements
-352x^2+6x=0
a = -352; b = 6; c = 0;
Δ = b2-4ac
Δ = 62-4·(-352)·0
Δ = 36
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{36}=6$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(6)-6}{2*-352}=\frac{-12}{-704} =3/176 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(6)+6}{2*-352}=\frac{0}{-704} =0 $
