I believe I have it right that the common factor of x^2+6x+8 and x^2+2x would be x^2 + 2x. If not let me know.......
But if those 2 terms were denominators of fractions what is the least common denominator?
nope
$\displaystyle x^2 + 6x + 8 = (x + 2)(x + 4)$ and $\displaystyle x^2 + 2x = x(x + 2)$But if those 2 terms were denominators of fractions what is the least common denominator?
thus, if combining two fractions with those quadratics as the denominators, the least common denominator would be: $\displaystyle x(x + 2)(x + 4)$
