Question

The sum of two integers is -1.The product of the integers is -72.Find the integers.

Answer 1

-9 and 8

x+y=-1.   Or.  y=-x-1

x*y=-72.   Or.   y=-72/x

Therefore

-x-1=-72/x

=-(x^2+x-72)

=(x-8)(x+9)

therefore the zeros are -9 and 8

Answer 2

-9 and 8. -9 + 8 = -1 and 8 x -9 = -72. Hope this helps.

Answer 3

8 and -9

Answer 4

integers means a whole number, either negative or positive. so the sum of -1 implies that the negative integer is 1 greater than the positive integer. So, what two numbers are 1 apart and multiplied together = 72? hint: the negative integer is -9.
