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.
If the sum of 2 numbers is 25 and their product is 156, the numbers are 12 and 13.
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
No - the product of numbers is the answer to a multiplication sum, while the sum of numbers is the answer to an addition sum.
Two numbers have a product of 80 their sum is 24?
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.

If the sum of 2 numbers is 25 and their product is 156, the numbers are 12 and 13.
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.
Any two odd numbers will have an odd product and an even sum.
There's no product or sum until you have at least two numbers.
