Question

please answer the 17th queste

Answer 1

since the remainder is not 0 so it is not a factor

Answer 2

Given f(x) = 3x^2 + x - 1.

Given g(x) = x + 1.

Apply remainder theorem,

= > x + 1 = 0

= > x = -1.

Plug x = -1 in f(x), we get

= > 3(-1)^2 + (-1) - 1

= > 3 - 1 - 1

= > 1.


The remainder is not equal to 0, therefore x + 1 is not a factor of 3x^2 + x - 1.


Hope this helps!
