Question

Find the least common denominator x^4/x^2+2x+1 and -8/x^2+5x+4

Answer 1

Answer:

(x + 4)(x + 1)(x + 1)   or (x + 4)(x + 1)²

Step-by-step explanation:

Factor both denominators and see what you are missing between them

(x^4)/[(x + 1)(x + 1)           -8/[x + 4)(x + 1)]

So in order to get a common denominator, we need

(x + 4)(x + 1)(x + 1) as a denominator, or (x +4)(x + 1)²
