Question

15 one..No spam..(if answer is 'no' How??​

Answer 1

Answer:

Let's check it

x+5=0

x=0-5=-5

-5³+2×-5²-14×-5+9

-125+(-50)+70+9

-175+79

=-96

which isn't equal to 0

hence (x+5) isn't a factor of the question

Answer 2

Answer:

No

Step-by-step explanation:

x=5

substitute in the equation

-125+50+70+9

=> -125+129

=> -4

so, x+5 is not a factor of x^3+2x^2-14x+9
