x^2-49/2x-1=x^2-14x+49/1-2x

Question

find the Domain, Lowest terms,Opposites, LCD, Build up

Answer 1

The equation can be written:

(x-7)(x+7)/(2x-1)=-(x-7)²/(2x-1), 2x-1 and 1-2x are opposites, that is, 2x-1=-(1-2x).

x+7=-(x-7)=7, because terms x-7 and 2x-1 cancel out.

x=0 is the only value of x to satisfy the equation, so the "domain" is zero. There is no other variable (no dependent variable). LCD=1 (the absolute value of 2x-1 when x=0).
