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.

the answer will be b x² +x-1
