The two numbers that sum to -4 and have a product of -21 are -7 and 3. When added together, -7 + 3 equals -4, and when multiplied, -7 × 3 equals -21.
3 and 7
3 and 7.
-21 has four factor pairs. (21,-1)(-21,1)(7,-3)(-7,3) None of them have a sum of -8.
20 x 21 = 420
There are no real numbers that satisfy the requirements. The complex solutions are: 1 +/- sqrt(21)
3 and 7
3 and 7.
35, 21
The numbers are 13 and 8 The product is 104
-21 has four factor pairs. (21,-1)(-21,1)(7,-3)(-7,3) None of them have a sum of -8.
31
Three and Seven
3 and 7 are the prime numbers because they cannot be divided by any number other than themselves and 1because 3+7 = 10 (Sum)and 3x7 = 21 (Product)
20 x 21 = 420
There are no real numbers that satisfy the requirements. The complex solutions are: 1 +/- sqrt(21)
There are none.
The two numbers are 21 and 7.
