Adding Rational Expressions Same Denominator

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.

Find the LCD of the following rational numbers

• 12

• 5

• 24

• 7

Find the LCD of the following rational expression

5/(x+8) and 2x/(x-3)

• (x+8)(x-3)

• 8x(x+2)

• (x²+3x+24)

When adding or subtracting rational expression with the same denominator...

• Add or subtract the denominators

• Add or subtract the numerators

• Add or subtract both denominator and numerator
