Answer:
14x^3 LCD
(35x+4) / 14x^3
Step-by-step explanation:
5 /2x^2 + 2 / 7x^3
We need to find the least common denominator
2x^2 =2 *x*x
7x^2 = 7*x*x*x
x*x is common so we need to multiply that by 2*7*x
The least common denominator is 2*7*x*x*x = 14 x^3
To add the two, multiply to get the common denominator)
5/2x^2 * (7x/7x) + 2/7x^3 *(2/2)
35x/14x^3 + 4/14x^3
(35x+4) / 14x^3
