4. Using the Method of Completing the square, find the zeroes of the following function to the nearest hundredth.
F(x)=2x^2+12x+5

Given:

The function is:

To find:

The zeroes of the given function by using the Method of Completing the square.

Solution:

We have,

It can be written as:

By Method of Completing the square add and subtract square of half of coefficient of x in the parenthesis.

For zeroes, F(x)=0.

Taking square root on both sides, we get

and

and

Therefore, the zeroes of the given function are -0.45 and -5.55.

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
