Question

Which of the following is the product of the rational expressions shown

below?
2/x+1 • 5/3x

A. 5(x+1)/6x
B. 5/x^2+3
C. 10/3x+3
D. 10/3x^2+3x

Answer 1

D. 10/3x^2+3x

Explanation:

The product of the two rational expressions is:

(2/x+1) * (5/3x)

Multiply the numerator of the first fraction by the numerator of the second fraction and the denominator of the first fraction by the denominator of the second fraction:

(2*5) / (x+1) * (3x)

Which simplifies to:

10 / (x^2 + x)

So the correct answer is:

D. 10/3x^2+3x
