Answer:
Step-by-step explanation:
Let's assume (x + 5) is the factor of f(x) = x^3 − 4x^2 + 3x + 7
then f(-5) should be equal to zero. Verifying:
Since -233 ≠ 0, the statement is false, so (x + 5) is not a factor of given polynomial
No
3x-8+3x+7-(simplified)-> 6x-1, which does not have (x+5) as a factor
Answer: it's A
Step-by-step explanation: Its A I bet nonono C
7 is the most common in this expression.
therefore to factorise, you will choose the most common factor.
the answer will be -7(r+5x)
