<u>Plotting </u><u />
Step 1: determine the y-intercept
- plot the point as the first point on the graph
Step 2: Move 2 units up, and 1 unit left (keep repeating this process until you have reached the limit of the graph)
Step 3: Go to the other side of the graph of the first point (y-intercept)
- move 2 units down, and 1 unit right keep repeating this process until you have reached the limit of the graph)
<em>When you've completed this process, it should look like this:</em>
Answer:
Step-by-step explanation:
Factorise the numerator and denominator
8a² - 2 ← factor out 2 from each term
= 2(4a² - 1) ← 4a² - 1 is a difference of squares
= 2(2a - 1)(2a + 1)
4a² + 4a + 1 ← is a perfect square
= (2a + 1)²
Thus
= ← cancel (2a + 1) on numerator/ denominator
=
=
