Which of the following is the quotient of this rational expression
Answer:
A
Step-by-step explanation:
Factor, where possible the numerators/ denominators
x² + x = x(x + 1) ← common factor of x
We can express the division as multiplication by leaving the first fraction and turning the second fraction upside down, that is
[tex]\frac{2x-1}{x+1}[/tex] × [tex]\frac{x(x+1)}{3x^2}[/tex]
Cancel the factor x and x + 1 on the numerator/denominator leaving
[tex]\frac{2x-1}{3x}[/tex] → A
Answer:
(2x - 1) / 3x.
Step-by-step explanation:
2x - 1 / (x + 1) / 3x^2 / (x^2 + x)
Invert the second fraction and multiply:
= (2x - 1) / (x + 1) * (x^2 + x) / 3x^2
= (2x - 1 ) / (x + 1) * x(x + 1) / 3x^2
= x(x + 1)(2x - 1) / 3x^2(x + 1)
x(x + 1) is common to top and bottom of the fraction so we divide both be x(x + 1) to give:
(2x - 1) / 3x (answer).
