Operation on Rational Expression

• A.
• B.
• C.
• D.

Divide

• A

• B

• C

• D

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.

Multiply

• A.

• B.

• C.

• D.

My first step will be to change the operator to multiplication and reciprocate the second fraction when...

• Adding

• Subtracting

• Multiplying

• Dividing

Subtract

• A

• B

• C

• D

Find the least common denominator of the expression

• 18

• 6x

• 3xy

• 6xy

Simplify the expression

• (-17x - 12y) / 15x

• (23x - 4y) / 15x

• (-17x - 4y) / 15x

• (-3x - 4y) / 8x

Multiply and Simplify

• 4(x+3)/(x+2),

• (x+2)/4(x+1)

• (x+2)/4(x+3),

• 4(x+1)/(x+2),

Simplify. 

• (m+6)/(m-3)

• 7/(m-3)

• 7(m+6)

• (m-3)
