Step 1:

\

The quardratic equation is \"\".

\

Write the equation in the form of \"\".

\

Rewrite the quadratic equation.

\

\"\".

\

Here \"\", \"\" and \"\".

\

Quadratic formula :

\

The solution of the quadratic equation in the form \"image\" is \"image\".

\

Substitute \"\", \"\" and \"\" in the quadratic formula.

\

\"\"                   (Quadratic formula)

\

\"\"  (Substitute  \"\", \"\" and \"\")

\

\"\"                           (Multiply)

\

\"\"                              (Simplify)

\

\"\"                            (Substitute  \"\")

\

\"\"                                (Simplify)

\

Therefore the solutions of the quadratic equation are \"\".

\

Solution:

\

The solutions of the quadratic equation are \"\".

\

Option \"\" is right choice.

\

Quetion 2: 

\

Step 1:

\

The quardratic equation is \"\".

\

3\"\"

\

Write the equation in the form of \"\".

\

Here \"\", \"\" and \"\".

\

Quadratic formula :

\

The solution of the quadratic equation in the form \"image\" is \"image\".

\

Substitute \"\", \"\" and \"\" in the quadratic formula.

\

\"\"                    (Quadratic formula)

\

\"\"         (Substitute  \"\", \"\" and \"\")

\

\"\"                      (Multiply)

\

\"\"                           (Simplify)

\

\"\"                         (Substitute  \"\")

\

\"\"                             (Simplify)

\

\"\"                                   (\"\")

\

\"\"                              (Take out common factors)

\

\"\"                                     (Cancel common terms)

\

Therefore the solutions of the quadratic equation are \"\".

\

Solution:

\

The solutions of the quadratic equation are \"\".

\

Option \"\" is right choice.
