The model represents x2 - 9x + 14
which is a factor of x2 - 9x + 14?
ox-9
ox-2
x+5

Step-by-step explanation:

The expression can be factored using the factors of 14, 2 and 7, which add to give 9.

  x² -9x +14 = (x -2)(x -7)

One of the factors is (x -2).

x - 2

Step-by-step explanation:

To factorise the quadratic

Consider the factors of the constant term (+ 14) which sum to give the coefficient of the x- term (- 9)

The factors are - 7 and - 2, since

- 7 × - 2 = + 14 and - 7 - 2 = - 9, thus

x² - 9x + 14 = (x - 7)(x - 2) ← in factored form

Thus (x - 2) is a factor of the expression
