Answer:
The factored form of given polynomial is 
Step-by-step explanation:
Given the polynomial 
We have to factor the above polynomial completely.

Take
common from each term.

Here, the quadratic polynomial is prime i.e it cannot be factored into lower degree polynomial. It has complex roots.
Hence, the factored form of given polynomial is 
This is a GEOMETRIC sequence as each number is being multiplied by 1/4
<h3>The measure of angle y is 35.68 degrees</h3>
<em><u>Solution:</u></em>
Given that,
hypotenuse 12
Opposite 7
Find the measure of angle y
y is unknown and is between the hypotenuse and adjacent side
The figure is attached below
In a right triangle, the sine of the angle is the ratio of the side opposite to the angle to the hypotenuse
Therefore,

Thus measure of angle y is 35.68 degrees
