To find the answer to "What two numbers have a product of 22 and a sum of -107?" we first state what we know. We are looking for x and y and we know that x • y = 22 and x + y = -107.
Before we keep going, it is important to know that x • y is the same as y • x and x + y is the same as y + x. The two variables are interchangeable. Which means that when we create one equation to solve the problem, we will have two answers.
To solve the problem, we take x + y = -107 and solve it for y to get y = -107 - x. Then, we replace y in x • y = 22 with -107 - x to get this:
x • (-107 - x) = 22
Like we said above, the x and y are interchangeable, therefore the x in the equation above could also be y. The bottom line is that when we solved the equation we got two answers which are the two numbers that have a product of 22 and a sum of -107. The numbers are:
-106.794
-0.206
That's it! The two numbers that have a product of 22 and a sum of -107 are -106.794 and -0.206 as proven below:
-106.794 • -0.206 ≈ 22
-106.794 + -0.206 = -107
Note: Answers are rounded up to the nearest five decimals if necessary so the answers may not be exact.
