Solved Examples

Question 1: Simplify $\frac{x^2 - x - 2}{x^2 - 4x - 5}$
Solution:
Given, $\frac{x^2 - x - 2}{x^2 - 4x - 5}$

Step 1:
Find the factors of quadratic equations

x2 - x - 2 = x- 2x + x - 2

= x(x - 2) + (x - 2)

= (x + 1)(x - 2)

and

x2 - 4x - 5 = x2 - 5x + x - 5

= x(x - 5) + (x - 5)

= (x + 1)(x - 5)

Step 2:

=>
$\frac{x^2 - x - 2}{x^2 - 4x - 5}$ = $\frac{(x + 1)(x - 2)}{(x + 1)(x - 5)}$

= $\frac{x - 2}{x - 5}$

=>  $\frac{x^2 - x - 2}{x^2 - 4x - 5}$ = $\frac{x - 2}{x - 5}$

 

Question 2: An amusement park is planning a circular ride for children. If the radius of the circle is 14 feet, what is the area.
Solution:
Given
Radius of the circle (r) = 14

Let the area of circle = A  

Use the formula, A = ∏ r2 , where ∏ = $\frac{22}{7}$

=> A = $\frac{22}{7}$ * (14)2

=> A = $\frac{22}{7}$ * 14 * 14

=> A = 616 square feet.

Hence, area of the circular field id 616 square feet.

 

Question 3: The sum of three rational numbers is 3. If two of the numbers are $\frac{-3}{10}$ and $\frac{5}{15}$. Find the third number.

Solution:
Sum of the three numbers = 3

Two of the numbers are $\frac{-3}{10}$ and $\frac{5}{15}$

Step 1:
Sum of two numbers

=> $\frac{-3}{10}$ + $\frac{5}{15}$ = $\frac{-9 + 10}{30}$

= $\frac{1}{30}$

Step 2:

To find the third number, subtract sum of two numbers form the 3

=>  Third number = 3 - $\frac{1}{30}$

=
$\frac{90 - 1}{30}$

=
$\frac{89}{30}$

  Hence the third number is $\frac{89}{30}$.
