There are an infinite number of real numbers that multiply to get 72.
-73
Well, isn't that a happy little question! If we're looking for two numbers that multiply to 72, we can think of them as partners dancing together. One pair that comes to mind is 8 and 9 - when they twirl and spin together, they create the beautiful number 72. Remember, there are many different pairs of numbers that can work together in harmony to create 72, so feel free to explore and find the one that speaks to you!
72
Let the two numbers be a and b. Then,ab = 72 therefore b = 72/a. Substituting for b in a + b = -19 gives,a + 72/a = -19 : multiply both sides by a.a2 + 72 = -19a : therefore a2 + 19a + 72 = 0Solving for a quadratic equation gives,a = [-19 ± √(361 - 288)] ÷ 2 which simplifies to a = -9.5 ± 4.272 (3dp)The two numbers are therefore -9.5 + 4.272 = -5.228 and -9.5 - 4.272 = -13.772
The two numbers that multiply to -72 and add to -29 are approximately 3.57 and -32.57.
The two numbers are... -36 and -36
There are an infinite number of real numbers that multiply to get 72.
There are infinitely many pairs. Two possibilities are: 1 * 72 10 * 7.2

two consecutive factors of 72 are 8 and 9. 8 and 9 are consecutive and when you multiply it you'll get 72.. 8 x 9 = 72
Let the two numbers be a and b. Then,ab = 72 therefore b = 72/a. Substituting for b in a + b = -19 gives,a + 72/a = -19 : multiply both sides by a.a2 + 72 = -19a : therefore a2 + 19a + 72 = 0Solving for a quadratic equation gives,a = [-19 ± √(361 - 288)] ÷ 2 which simplifies to a = -9.5 ± 4.272 (3dp)The two numbers are therefore -9.5 + 4.272 = -5.228 and -9.5 - 4.272 = -13.772
72 = 1*72 = 2*36 = 3*24 = 4*18 = 6*12 = 8*9
