It would appear that x2 is meant to be x-squared.
Since you have been able to use the - sign (for 20x), I am assuming the missing symbol before 280 is not "-".
But if it is "+", then the expression does not have real factors. If you are OK with complex factors, then you should be advanced enough not to ask this question.

What is the point of intersection of the parabolas y equals x2 plus 20x plus 100 and y equals x2 -20x plus 100 showing work?
If: y = x2+20x+100 and x2-20x+100 Then: x2+20x+100 = x2-20x+100 So: 40x = 0 => x = 0 When x = 0 then y = 100 Therefore point of intersection: (0, 100)
What number must you add to complete the square of x2 plus 20x equals 39?
x2 + 20x - 39 = 0: Add 61 giving: x2 + 20x + 100 = (x + 10)2
X2 plus 20x plus 4 equals 0?
x2 + 20x + 4 = 0 x2 + 20x + 100 = 96 (x + 10)2 = 96 x + 10 = ±961/2 x = -10 ±961/2 x = -10 ±4√6

280
X2 plus 36 equals 20x?
x2 + 36 = 20x so x2 - 20x + 36 = 0 so x2 - 2x - 18x + 36 = 0 or x(x - 2) - 18(x - 2) = 0 that is (x - 2)(x - 18) = 0 so x - 2 = 0 or x - 18 = 0 ie x = 2 or x = 18
