How do I determine if there are common factors for x^5+3x^3+5x/4X^4+2x^2, when the leading coefficient of the denominator is greater than that of the numerator, and there is no constant in the numerator - thus making using the roots calculator impossible, and long division. I ...

Factor the numerator and denominator of each fraction if neceesary. Rewrite each one as a product. Then look for ones and simplify. The denominator is not zero. x^2+6x+9 2x^2-x-10 28x^2-x-15 -------- --------- ---------- x^2-9 3x^2+7x+2 28x^2-x-15 x^2+4x ------- 2x+8

how would i find least common multiple of 20, 50 and 3 ? okay well you take the 50 and times it by ever number 50--> is it divisbile by 3 NO so not the least common multiple 50x2=100 --> is it divisible by 3 NO, so not the least common multiple 50x3=150 --> is it ...

How do you do?: x^2+1 ----- x^4-1 Thanks! Try to factor wherever you can so you can reduce as much as you can. Factors of x^4 - 1 are (x^2 + 1)(x^2 - 1). Now we have: x^2 + 1 ------------------ (x^2 + 1)(x^2 - 1) Do you see a common factor to cancel out in both the numerator (...
