B. 5a + 1
C. 2a - 4
D. 5a -4

Answer 1

familiar wid synthetic division ?

Answer 2

no :/

Answer 3

okay, another way is to factor the numerator

Answer 4

\[ (5a^2−14a−3)÷(a−3) =\frac{ (5a^2−14a−3)}{(a−3)}\]
\[=\frac{ (5a^2−15a+a−3)}{(a−3)}=\frac{ [5a(a−3)+1(a−3)]}{(a−3)}\]
\[=\frac{ (5a+1)(a−3)}{(a−3)} =(5a+1)\]
Thus (5a+1) is the simplified form of the given fraction.
