7) Certainly there is a typo in the statement, just see that the expression of item (ii) is different from that of item (i). Probably the correct expression is:

. With this consideration, we can continue.
(i) Let E the expression that we are analyzing:

Since (x-1)² is a perfect square, it is a positive number. So, E is a result of a sum of two positive numbers, 2(x-1)² and 3. Hence, E is a positive number, too.
(ii) Manipulating the expression:

So, it's the case when E=0. However, E is always a positive number. Then, there is no real number x that satisfies the expression.
8) Let E the expression that we want to calculate:

Multiplying by (2-1) in the both sides:

Repeating the process, we obtain:
Answer:
Expression
Step-by-step explanation:
2,3, and 7 are coefficient .
x and y are constant
Answer:
The answer is 34, bec what you do is: 67 - 33.
<span>They are the values of 'x' that make the function zero.
If you graph the function, they are the values of 'x' where the graph
crosses the x-axis.</span>
