Question

The expression y2 – 10y + 24 has a factor of y – 4. What is another factor of y2 – 10y + 24?

Answer 1

We may answer the question above by dividing the expression y² - 10x + 24 with the given factor, y - 4. The division would give an answer of y - 6. Thus,

                                y² - 10x + 24 = (y - 4)(y - 6)

The answer is the fourth choice, y - 6.
