The sum of two integers is -8 and their product is plus 7 what are the two integers?
short answer -1 and -7 long worked answer let x = one of the integers let y = the other integer x+y = -8 xy = 7 solve for y y = -8 - x plug y in x(-8 - x) = 7 rearrange -x^2 - 8x - 7 = 0 divide both sides by -1 x^2 + 8x + 7 = 0 factor (x + 7)(x + 1) = 0 x = -1, -7 y = -8 - x so y = -8 + 1 = -7 or -8 + 7 = -1 so when x = -1, y = -7 when x = -7, y = -1

What is x if sqrt of x plus 8 equals 7?
If √x + 8 = 7, then √x = -1, so x does not exist, because √ only refers to positive roots.If √(x + 8) = 7, then x + 8 = 49 and x + 41.
