Find the least common denominator of the expression

• 18

• 6x

• 3xy

• 6xy

When adding and subtracting rational expressions, my first step should be to:

• Combine like terms in the numerators.

• Determine a Least Common Denominator.

• Factor all of the numerators and all of the denominators.

• Change the operator to multiplication and reciprocate the second fraction.

20x³/(5x+10)

• 4x³/(x+2)

• 4x³/(x+10)

• 2x³/(5x+1)

• 2x³/(x+5)
