Question

simplify the sum.....

d^2-7d+12/d^2-d-6 + d^2+5d+6/d^2-2d-15

Answer 1

Are the two terms 12/d^2 and 6/d^2 fractions? Just clarifying. Could also be division by all following terms.

Answer 2

i think so

Answer 3

Then I think the answer is (2d^4 - 5d^3 -21d^2 +18)/d^2

Answer 4

If you don't need a common denominator, then the answer is 2d^2 - 5d - 21 +18/d^2
