if a=b and c=0 then a over c and b over c . why is c=o important?if we tried to solve an equation by dividing both sides by zero?

Question

i need help dont understand ot

Answer 1

c=0 is important because if c is the denominator, the equation will be undefined.  This is because we cannot divide by zero.  When graphing an equation, c is a vertical asymptote because the graph never reaches the value, though it gets closer and closer to it.  c is a restriction.
