Do you need the expanded notation form, or expanded factor form?
Answer:
<em>LCM</em><em> </em><em>of</em><em> </em><em>12</em><em> </em><em>and</em><em> </em><em>10</em><em>=</em><em> </em><em>60</em>
<em>hope</em><em> </em><em>this helps</em><em> </em><em><</em><em>3</em>
Your answer would be (b.) because -2+-3=-5
Answer:

Step-by-step explanation:
The standard form of a quadratic is:

To complete the square, the a (leading coefficient) must be 1 and there can only be terms with variables on one side.
The expression given:

follows these rules. Next, we divide the b (linear coefficient) by 2, then square it. Basically:

The b in the expression is -18.


This is the number that is added.
