Let's denote the two numbers as x and y. We know that xy = A and x + y = 4. To find the two numbers, we can use the factoring method. We can rewrite the second equation as y = 4 - x and substitute this into the first equation to get x(4 - x) = A. This simplifies to x^2 - 4x + A = 0. We can then solve this quadratic equation to find the values of x and y.

The numbers are 10 and 5.2
-9+4
-5 + √21 ≈ -0.4174 -5 - √21 ≈ -9.5826
-2
-125
2.4115 and 33.5885 (to 4 dp)
(9 - √89)/2 ≈ -0.217 and (9 + √89)/2 ≈ 9.217
Ah, what a happy little question! To find two numbers that multiply to 900, we can think of numbers that divide evenly into 900. One pair of numbers that work beautifully is 30 and 30. When you multiply 30 by 30, you get 900. Just like that, we've created a lovely little math masterpiece!
