Question

Write each fraction in terms of the LCM of the denominators.

x+1 over x+5
x+3 over x-8
4 over 40+3x-x2

Answer 1

what doest it mean in "terms of the LCM of the denominators."?

Answer 2

40+3x-x^2 = -(x-8) (5+x)
x-8
x+5
40+3x-x^2 is the LCM

Answer 3

so i think that this sign low common denominator and in case of those fravction i think that will be x2-3x-40=(x-8)(x+5)
