<u>Answer:</u>
x = ±5
<u>Step-by-step explanation:</u>
We are given the following polynomial function and we are to find all of its real roots:

Let
so we can now write it as:

Factorizing it to get:



Substitute back
to get:

The quadratic factor has only complex roots. Therefore, the real roots are x = ±5.
The slope of this line is -1 you find this by using the slip formula of y-y over x-x find two points on the line so I used points (-2,2) and (-1,1) plug them into the formula to get the slope of -1 hope this helps:)

Step-by-step explanation:
reasons
1:sum of all side of triangle is 180 degree(here is 220)
3: try in copy and u will able to solve
4:first of all make 9 cm as shown in figure and draw 15 . finally measure the remaining side.
5: 3y+5y+y=180
9y=180
hence,y=20
