True [87]4 years ago
8 0

Answer:

\dfrac{5x^2-3x+8}{2x+1}

Step-by-step explanation:

The denominators are the same, so the numerators can be added in the usual way.

... = ((5x^2 +6) -(3x -2))/(2x +1)

... = (5x^2 +6 -3x +2)/(2x +1)

... = (5x^2 -3x +8)/(2x +1)

The numerator and denominator have no common factors, so this cannot be reduced further.
