The product of two numbers is 144. If one number is 9, the other will be ______ |
|
Answer» The EASIEST way is to use the following quadratic equation RELATED to sum and product: X² - SX + P =0, where S = sum and P = product X² - (-24)X + 144 = 0 X² + 24X + 144 = 0. Extract the roots: X' = [-b+√(b²-4ac)]/2a and X" = [-b-√(b²-4ac)]/2a X' = [-24+√(-24)²-4(1)(144)]/2 X' = (-24√0)/2 → X' = X" = -12 Then the 2 NUMBERS are -12 and -12Put your values in this method you will get the answer Step-by-step explanation: |
