What is the solution set for the open sentence with the given replacement set? x2 + 2 = x + 8, {1, 3, 4, 5}

bonufazy [111]

X^2 + 2 = x + 8
x^2 - x + 2 - 8 = 0
x^2 - x - 6 = 0
Input 1 => 1^2 - 1 - 6 = 1 - 1 - 6 = -6
Input 3 => 3^2 - 3 - 6 = 9 - 3 - 6 = 0
Input 4 => 4^2 - 4 - 6 = 16 - 4 - 6 = 6
Input 5 => 5^2 - 5 - 6 = 25 - 5 - 6 = 14

Solution set { -6, 0, 6, 14}
