There are an infinite number of pairs ... one positive and one negative ... that you can do that with.
If you stick to only whole numbers, then there are only 10 ways to do it:
The two numbers are... -36 and -36
-18 and -18
36
The next two square numbers after 30 are 36 and 49
(Solving with algebra)Lets call the two numbers x and y.We want to find x and y so that x + y = 15 and xy = 36.First, solve one equation for x or y. Here we will solve the first equation for x:x = 15 - yBecause we know that 15 - y = x, we can plug it into the second equation:(15 - y)(y) = 36.Solving the above equation will give us one of the numbers:Distribute: y^2 - 15y + 36 = 0Factor: (x - 12)(x - 3) = 0We can see here that the numbers are 12 and 3 (by solving for x).The numbers in this problem are simple enough that you can use guess and check.Start at a number (1, for example), and find the other number that would add to 15. If the numbers multiply to 36, then you found the two numbers. If not, try another one.The two numbers are 12 and 3.
Two numbers that you can multiply together to get 72 are: 36 and 2.
The two numbers are -12 and 36
The two numbers that add to 38 and multiply to give 72 are 36 and 2. When you add them together, 36 + 2 equals 38, and when you multiply them, 36 × 2 equals 72.
The two numbers are... -36 and -36
+6 and also -6
How about: 4*9 = 36 as one example
The numbers are 3 and -12
The two numbers that add to get negative 36 and multiply to get negative 144 are -48 and 12. When you add them, -48 + 12 equals -36, and when you multiply them, -48 × 12 equals -144.
Two will do as for example 4 times 9 = 36
The two numbers that add up to -36 and multiply to 324 are -18 and -18. This is because -18 + -18 equals -36, and -18 * -18 equals 324.
