Question

The expression y2 – 10y + 24 has a factor of y – 4. What is another factor of y2 – 10y + 24? y – 20 y – 14 y – 8 y – 6

Answer 1

(y-6)

Explanation:

`y^2 - 10y + 24`

We need to find out two factors whose product is 24 and sum is -10

-6 times -4 = 24

-6 + -4 = -10

So two factors are -6 and -4

We write the factors inside the parenthesis

(y-6) (y-4)

Factor (y-4) is already given

So another factor is (y-6)
