What are the factors of -8 that when added equal -4?

Answer 1

-104

Answer 2

Write two equations

xy = -60

x+y=-44

use substitution to solve

y=-60/x

x+(-60/x)=-44

x2+44x-60=0

ax2+bx+c=0

use quadratic equation to find both values for "x" and only one will work.

[-b+-sqrt(b2-4(a)(c)]/2a

-44+-sqrt(1936-4(1)(-60)) / 2

x = 1.323807579 and -90.64761516

put both into the second equation

y = -44 - 1.323807579

y = -44 - -90.64761516

y = -45.32380758 and 46.64761516

Now you have to find which combination of "x" values and "y" values satisfy each equation

When you do this you find that x=1.323807579 and y=-45.32380758

so the factors are 1.323807579 and -45.32380758

Answer 3

-18 and -3 are factors of -54, multiply to 54 and add to -21. It's slightly different from the question you asked, but I think that's what you meant.

Answer 4

-8 and 4
