Answer:
A.
[tex] \frac{ {7x}^{2} - 5x + 1}{4x + 1} [/tex]
Step-by-step explanation:
Since the denominators are the same we just have to combine the top.
[tex] {x}^{2} - 5x + {6x}^{2} + 1[/tex]
Combine alike terms.
[tex] {7x}^{2} - 5x + 1[/tex]
put that over our denominator.
[tex] \frac{ {7x}^{2} - 5x + 1 }{4x + 1} [/tex]
