Answer:
C
Step-by-step explanation:
to factor x² - x - 2
consider the factors of the constant term which sum to give the coefficient of the x-term.
the factors are - 2 and + 1 since - 2 × 1 = - 2 and - 2 + 1 = - 1
x² - x - 2 = (x - 2)(x + 1), hence (x + 1) is a factor
The relationship between (x + 1) and the polynomial x² - x - 2 is that ( x + 1) is a factor of x² - x - 2.
What is a polynomial?
A mathematical expression of one or more algebraic terms each of which consists of a constant multiplied by one or more variables raised to a non negative integral power.
How to know whether there is any relation between (x + 1) and the polynomial x² - x - 2?
The given polynomial is x² - x - 2.
- Here we should try to factorise the polynomial.
x² - x - 2
= x² - 2x + x - 2
= x( x - 2) + 1( x - 2)
=( x - 2) ( x + 1)
So we can see that, ( x + 1) is a factor of x² - x - 2.
So, option C is correct.
