x+y= 15 xy=56 y=15-x You take all of the and make it into x(15-x)=56 then you get -x(x)+15x=56 -x(x)+15x-56=0 Then we break it up (-x+7)(x-8)=0 Then we can solve for our two numbers which are -7 and -8. I think i am missing something though. Hope the rest of your homework goes better. You can pull the negative out of the equation to make it easier.
multiply by one if ur looking for the sum and divide by one if look ing for the product, easy

If you simply add numbers the answer is the sum of those numbers.
The sum of 72 and 12 is 84. The product of the two numbers is 864.
Numbers that have a product of 8 are 1,8 and 2,4. Their sums are 9 and 6 respectively. Numbers that have a product of 7 and a sum of 8 are 1 and 7.
the sum is -b/a and the product is c/a
Two numbers have a product of 80 their sum is 24?
NO!!! Product means Mu;ltiply Sum means Addition (Add).
Um, x2+3x-5=0? This is ax2+bx+c where a=1, b=3, and c=-5. The sum of the roots is -b/a so that means the sum of the roots is -3. Also, product of the roots is c/a. That means the product of the roots is -5. -3+(-5)= -8. There you have it.

the product of 3 whole numbers is 5. Their sum is 7. what are the numbers
The product is 1254. The sum is 79.

If the sum of 2 numbers is 25 and their product is 156, the 2 numbers would be 12 and 13.
First, we need to clarify the condition in the problem: the sum of two numbers is 16, and the difference between the two numbers is 6. Based on these conditions, we can say that these two numbers are respectively x and y. According to the problem description, we can list the following equations: The sum of the two numbers is 16, which is x plus y is equal to 16. The difference between the two numbers is 6, which is 6 x−y=6. By solving this system of equations, we get x=9 and y=7. So the product of these two numbers is 9 x 7 = 63
Any two odd numbers will have an odd product and an even sum.
