Question

Is(x+2)a factor of x^3+5x^2-7x+3​

Answer 1

Answer:

Not a factor

Step-by-step explanation:

To verify......

Using remainder theorem :-

x = -2

(-2)³ + 5(-2)² - 7(-2) + 3

-8 + 20 + 14 + 3

-8 + 37

29

Since, 29 is not equal to zero

Therefore, (x+2) is not a factor of x³ + 5x² - 7x + 3
