Answer:
You have to add them then dived
Step-by-step explanation:
<h2>x² - x - 12</h2><h2 />
Start by setting up your two sets of parenthses.
X² breaks down into x and x.
What we are looking for is factors of the constant term
that add to the coefficient of the middle term.
The question is, what is the coefficient of the middle term
in this problem if there is nothing written in front of the x.
Well if there is nothing written there,
the coefficient is understood to be 1.
So what we are looking for are factors of -12 that add to -1.
<em><u>Factors of -12</u></em>
+12 · -1
-12 · +1
+6 · -2
-6 · +2
+4 · -3
-4 · + 3
We can see that -4 and +3 add to -1.
So they go in the second position of each binomial.
This gives us (x - 4)(x + 3) as our answer.
The next step she should take is to use her ruler to join the given point to the point where the arcs intersect.
<h3>Steps in constructing perpendicular lines</h3>
- Place your compass on the given point
- Draw an arc across the line on each side of the given point. Do not adjust the compass width when drawing the second arc
- From each arc on the line, draw another arc on the opposite side of the line from the given point. The two new arcs will intersect.
- Use your ruler to join the given point to the point where the arcs intersect.
- Use your compass and ruler to draw a perpendicular line from each given point to the line segment
From this, we can deduce that her next step is to use her ruler to join the given point to the point where the arcs intersect
Thus, the next step she should take is to use her ruler to join the given point to the point where the arcs intersect.
