Question

what is the LCD for these two rational expressions?
Please Help!
y^4 3
-------- ---------
y^(2)-6y+9 y^(2)+y-12

Answer 1

can you factor the denominator on the left and also the one on the right?

Answer 2

(3 + -1y)(3 + -1y) (-4 + -1y)(3 + -1y)

Answer 3

(3 + -1y) is in both sides, but the left side has two of them
the right side has factor (-4+ -1y)
so
the lcm = (3 + -1y)(3 + -1y)(-4 + -1y)

Answer 4

ahh ok ty
