Correct Question is: Find the illegal values of b in the fraction (2b^2 + 3b - 10)/(b^2 - 2b - 8)
illegal values are those which are not a part of Domain. In this case these will be such values which will make the denominator of the fraction zero.
So setting the denominator equal to zero, we can find these values.
Thus, b=-2 and b=4 are the illegal values for this expression

Answer:
14 ft
Step-by-step explanation:
Given:
- Bedroom is 4 ft longer than it is wide.
- Area is 252 ft².
Let x = width of the bedroom:
- width = x ft
- length = (x + 4) ft
Therefore:
To find the value(s) of x, complete the square.
Add the square of half the coefficient of the term in x to both sides:
<u>Factor</u> the perfect trinomial on the left side:
<u>Square root</u> both sides:
Therefore:
As width cannot be negative, the width of the room is 14 ft.
