1. Explain why the equation x+1/x-3 = 4/x-3 has no solution.
2 What are the domain restrictions for the following expression: 2x-8 / x^2-6x+8 and why are these values restrictions?
x+1=4⇒x=3however 3 is not in the domain of either side of the equation (no division by 0)
again the point is no dividing by 0x2−6x+8=(x−4)(x−2)=0 when x=4, or x=2Thus neither 4 nor 2 are included in the domain
