Step-by-step explanation:

The zeroes ( = x-intercepts) are x = -3 and x = -1.

So the x -coordinate of the vertex is between x = -3 and x = -1.

The actual x-coordinate is halfway between these value: at x = -2.

To cancel a term.its necessary to add the _____to both sides of the equation

ahrayia [7]

Answer:

To cancel a term, it is necessary to add the <em>opposite of the term</em> to both sides of the equation

Step-by-step explanation:

Adding opposites creates a sum of zero. Zero added to anything else does not change the its value. So, adding the opposite of a term effectively removes it from (that side of) the equation.
