Rewrite 2x2−x−12 and 1x2−16 as equivalent rational expressions with the lowest common denominator.

are the rational expressions.

Step-by-step explanation:

To rewrite and as equivalent rational expressions

i.e.

By factorization:

By multiply both sides with ( x+3) & (x+4), we get:

are the rational expressions

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
