Question

Adding and subtracting Rational equations!!!!! please help me ASAP ?!?!?!?!?!?!?!?!?!?!?!!?!?!?!??!!?!?Add. 2/9x^3+5/3x

Answer 1

`(2)/(9x^3) + (5)/(3x)`

Find the LCD .

Factor each denominator into its primes

9 = 3²

Find the least common denominator 3²x³ = 9 x³

Adjust fractions based on the LCD:


`(2)/(9x^3) + (5*3x^2)/(9x^3)`

Since the denominators are equal, combine the fractions :


`(2+3*5x^2)/(9x^3)`

Simplify 2+3*5x²

multiply the numbers : 3 * 5 = 15

2 + 15 x²


`= (2+15x^2)/(9x^3)`

hope this helps!
