X= - 13, 1

x2 + 12x - 13 = 0, add 13 to both sides

x2 + 12x = 13, add 62 to both sides to complete the square

x2 + 12x + 62 = 49

(x + 6)2 = 49, take the square root to both sides

x + 6 = ± √49, subtract 6 to both sides

x = -6 ± 7

x = -6 + 7 = 1 or x = -6 - 7 = -13

Q: What is x when x to the second power plus 12x-13 equals 0?

It equals 0. * * * * * Unless the question is (-x)2 + (+x)2. In that case, the answer is 2x2

If: y2+x2 = 52 Then: x2 = 52-y2 Their values could be: x = 3 and y = 4

If 2+3 5s 5 squared is 25 then 25 times 2 equals 50

It would be 4 because 2 to the second power is really 2 * 2, which equals 4.
