It is 44. The reason is that 44 = 11 X 4 and 11 + 4 =15.
Well, well, well, aren't we getting fancy with our math riddles? The two numbers you're looking for are 20 and 4. They multiply to 44 and add up to 24. So there you have it, math whiz!
To factor a trinomial (three-term expression) of the form n2+bn+c, find the two numbers h and k that are factors of c and add up to b. Then, write those numbers in this template: (n+h)(n+k) For the trinomial n2+7n-44, c = -44 and b = 7. The two numbers that are factors of -44 and add up to 7 are 11 and -4. So, the factored form would be (n+11)(n-4).
