Rational Expressions Adding Like Denominators

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.

• k = 7
• x = 7.1
• x = 7.6
• x = 1/7

Perform the operation

• A

• B

• C

• D

• A
• B
• C
• D

Find the sum: (3x + 4) / 9x + (6x - 2) / 9x

• 1 + 3/9x

• 2 + 2/3x

• 4 + 1/9x

• 1 + 2/3x

Add the rational expressions:

Find the sum: (2x + 3) / 5x + (4x - 1) / 5x

• (6x + 2) / 5x

• (8x + 2) / 5x

• (2x + 7) / 5x

• (6x - 1) / 5x

Add the rational expressions:
