Answer:
C.7 ɪs ᴛʜᴇ ᴀɴsᴡᴇʀ
Step-by-step explanation:
The standard form of quadratic equation is ax² + bx + c = 0.
The given equation is x² - kx + 2 = 0. Since this equation is quadratic as well, then 2 is the value of c
Looking at the value c, 2, think of two numbers that when multiplied, they will result to 2. Bear also in your mind that the given equation has a negative k (-k), so the numbers to be multiplied should involve negative numbers. The focus is on -k as well because it will later be crucial in our next step.
