Question

this is a multiple choice.
To clear the equation (6/x) + 5 = 4/(x − 3) of fractions, multiply each side of the equation by the least common denominator ______.

a) x-3
b) x
c) x^2 -3
d)x(x-3)
c) x^2

Answer 1

I don't see your choice of answer.

hint:
I see two denominators, one is x, the other is x-3,
and neither one is a factor of the other.

e.g. suppose you have 1/4 + 2/7
wouldn't the LCD be 28 ? , how did I get that ?

Answer 2

how about

6/7 + 5 - 4/2

how do you find the LCD of that expression?
Do yours the same way.

Answer 3

my answer is x^2 -3

Answer 4

I got the correct answer: x(x-3). is this answer correct answer

Answer 5

I know that The LCM of a, b is the smallest multiplier that is divisible by both a and b

Answer 6

x(x-3) is correct, but it is x^2 - 3x, not x^2-3

LCM(a,b) is not a*b
LCM(a,b) = a*b / GCD(a,b)

LCM(6,8) is not 48. It is 24, which is 6*8/GCD(6,8) = 6*8/2

LCM = ab if a and b have no common factors, which Reiny sort of mentioned above.
