the model represents x² - 9x + 14. which is a factor of x² - 9x + 14? o x - 9 o x - 2 o x + 5 o x + 7
Answer
Explanation:
Step1: Factor the quadratic expression
We need to factor $x^{2}-9x + 14$. We look for two numbers that multiply to $14$ and add up to $-9$. The numbers are $-2$ and $-7$ since $(-2)\times(-7)=14$ and $-2+( - 7)=-9$. So, $x^{2}-9x + 14=(x - 2)(x - 7)$.
Answer:
B. $x - 2$
