To find the answer to "What two numbers have a product of -193 and a sum of 26?" we first state what we know. We are looking for x and y and we know that x • y = -193 and x + y = 26.
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 = 26 and solve it for y to get y = 26 - x. Then, we replace y in x • y = -193 with 26 - x to get this:
x • (26 - x) = -193
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 -193 and a sum of 26. The numbers are:
-6.0263
32.0263
That's it! The two numbers that have a product of -193 and a sum of 26 are -6.0263 and 32.0263 as proven below:
-6.0263 • 32.0263 ≈ -193
-6.0263 + 32.0263 = 26
Note: Answers are rounded up to the nearest five decimals if necessary so the answers may not be exact.
