    two numbers multiply together to make -15

    they add together to make 2

    What are the two numbers?

    Answer provided by our tutors

    let 'x' and 'y' be the numbers

    two numbers multiply together to make -15

    x*y = -15

    they add together to make 2

    x + y = 2 = > y = 2 - x

    lets plug y = 2 - x into x*y = -15 we get

    x(2-x) = - 15

    by solving the above quadratic equation we find two roots

    x1 = 5

    x2 = -3

    For x = 5, y = 2 - 5 = -3

    indeed 5*(-3) = - 15 and 5 + (-3) = 2

    one solutions is x = 5, y = -3.

    For x = -3, y = 2 - (-3) = 5

    indeed (-3)*5 = - 15 and -3 + 5 = 2

    second solutions is x = -3, y = 5.


    Welcome to the fastest and best online Factoring Calculator.

    It is easy to use! Simply enter a number below, then press "Factor" and we will calculate all the factors for that number.

    A factor of a number is an integer that you can multiply with another integer to get that number. All numbers have 1 and the number itself as factors.

    A number divided by one of its factors will equal an integer and be one of the number's other factors.

    For instance, let's use 12. You want to find which two numbers multiplied together equal 12, or in other words, which numbers divide evenly into 12 with no remainder.


    Most numbers have many factors. Our popular Factoring Calculator above will display all the factors for any number you enter.

    Note that your teacher may refer to this Factoring Calculator as the Factorization Calculator. Factoring Calculator and Factorization Calculator mean the same thing.

    Factoring Large Numbers
    Our Factoring Calculator can calculate the factors of any number up to 99,999,999. However, note that it uses Javascript that is running in the browser on your computer.

    Calculating numbers under a million is fast on most computers, but some higher numbers may take a few seconds to calculate if you have a slower, older computer.

    If you have the sum of two numbers as well as the product those numbers, you can use this online calculator to calculate the actual numbers for you:

    What two numbers multiply to and add to

    This is especially useful for factoring trinomials, such as x2+7x+12, by entering the coefficients into the calculator. For example, if you make X*Y=12 and X+Y=7, then you find that X=4 and Y=3. You can then rewrite the trinomial in its factored form, (X+4)(X+3).

    What numbers multiply to 6 and add to 4?

    Given, the sum of two numbers is 4 and their product is 6. We can see that the term inside the square root is negative and hence this function has no real solutions. This means no such real numbers exist such that they add up to 4 and multiply to 6.

    What are two numbers that multiply to 12 and add to 7?

    The two numbers that multiply to 12 and add to 7 are as follows:.
    Here is the math to prove that our answer to "What two numbers multiply to 12 and add to 7?" above is correct:.
    Multiply: 3 x 4 = 12..
    Add. 3 + 4 = 7. The answers above are rounded if necessary..

    What numbers multiply to 60 and add to 17?
