Answer:
<em>i: </em>x=-2, x=1
<em>ii: </em>x=-1/2
Step-by-step explanation:
Quadratic form:
You solve <em>i </em>by using FOIL (First, Outside, Inside, Last) because it is a multiplication problem.

<em>"first"</em> would be
, which would equal 
<em>"outside"</em> would be
, which would equal 
<em>"inside"</em> would be
, which would equal 
<em>"last" </em>would be
, which would equal 
Now you need to combine the terms so that they are one after the other

Combine like terms, and you should get:

i Solution
<em>You need to get the variable by itself.</em>
<em>Subtract two from both sides</em>

<em>Add one to both sides.</em>

ii Solution
<em>Add all the terms.</em>
