The sum of two numbers is 52. their product is 100. what is the answer?

{2, 52}

Step-by-step explanation:

Actually, there are two answers, not just one.

Let the numbers be x and y.  

Then their sum is x + y and equals 52.

Their product is xy and equals 100.

We need to solve this system of equations for both x and y.

Solving x + y = 52 for x, we get x = 52 - y.

Substituting this result into the other equation, we get:

(52 - y)y = 100

This is a quadratic equation:  52y - y² = 100, or

-y² + 52y - 100 = 0.

Alternatively, y² - 52y + 100 = 0

Let's solve this quadratic by "completing the square."

First, identify the coefficient of the y term.  It is -52.  Take half of that, obtaining -26, square this result, obtaining 676.  Add 676 to y² - 52y, and then subtract 676 from the result:

y² - 52y + 676 - 676 + 100 = 0.

Then (y -26)² = 576.

Taking the square root of both sides, we get:

y - 26 = ± 24, or:

y = 24 + 26 = 50, and also:

y = -24 + 26 = 2

Note that 2(50) = 100, as it must, and that

2 + 50 = 52 (also correct).

The two-part answer is {2, 52}.
