To find the answer to "What two numbers have a product of 174 and a sum of -110?" we first state what we know. We are looking for x and y and we know that x • y = 174 and x + y = -110.
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 = -110 and solve it for y to get y = -110 - x. Then, we replace y in x • y = 174 with -110 - x to get this:
x • (-110 - x) = 174
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 174 and a sum of -110. The numbers are:
-108.39476
-1.60524
That's it! The two numbers that have a product of 174 and a sum of -110 are -108.39476 and -1.60524 as proven below:
-108.39476 • -1.60524 ≈ 174
-108.39476 + -1.60524 = -110
Note: Answers are rounded up to the nearest five decimals if necessary so the answers may not be exact.
