Please help, describe the error in the solving the equation

3. The second line should be or

3. So the roots are or

Step-by-step explanation:

Step 1:

If the function equals 0, we substitute all the separate factors to 0.

We keep the variable on the left side while all the other values go to the right side.

The given equation is

Step 2:

As given in step 1, we substitute all the separate factors to 0.

So or

So the roots are

So the roots are or

step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
