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
How do you solve the equation for x -4 over 3x equals 1 over 7?

Which 3 numbers x up to 2744?
2744 = 1 x 1 x 2 x 2 x 2 x 7 x 7 x 7 Make 3 groups of these factors and multiply the numbers in each group to get 3 numbers, eg: {1}, {1}, {2, 2, 2, 7, 7, 7} = 1 x 1 x 2744 {1}, {1, 2}, {2, 2, 7, 7, 7} = 1 x 2 x 1372 {1, 2}, {1, 2, 7}, {2, 7, 7} = 2 x 14 x 98 {1, 2, 7}, {1, 2, 7}, {2, 7} = 14 x 14 x 14 There are many more such answers.
