The x coefficient is 2
Take half of 2 to get 2/2 = 1
Square 1 to get 1^2 = 1

Add and subtract 1 to the expression. This is the same as adding 0. 

x^2 + 2x + 2
x^2 + 2x + 2 + 0
x^2 + 2x + 2 + (1-1)
(x^2 + 2x + 1) + 2 - 1
(x+1)^2 + 1

Answer: (x+1)^2 + 1

The number z and −1.9 are additive inverses.
tia_tia [17]

Additive inverses are numbers that add up to zero, such as 1 and -1. Z is the additive inverse of -1/9, so z is 1.9.

1.9 + -1.9 =0.

Drag the -1.9 icon to just one mark to the right of -2 on the number line, since each dash equals 0.1.  Drag z to just one mark to the left of 2 on the number line.The sum will be zero, so drag the sum icon to 0 on the number line.
