X² +18x = 0
To complete the square we are going to use formula a² +2ab +b² = (a+b)²
x² +2*9*x = 0
x² +2*9x+9² = 9²
(x+9)² = 9²
√(x+9)² = +/-√9²
x+9 = 9, or x+9 = -9
x=0, or x= - 18
The equation could be solved different way
x² +18x = 0
x(x+18) = 0
x=0 or x+18=0
x=0 or x=-18

First we need to figure out: What is quadrant II about?
As said in the picture provided, quadrant II is in the upper left corner of a graph.
For a point to be in QII, the <em>x values need to be negative</em>, and <em>the y values need to be positive</em>.
B: (-4,2) and D: (-3,5) would belong in QII.
<em>Their x values are negative, and the y values are positive. </em>
<em>Therefore, </em><em>B and D would be the correct answers.</em>
