The coefficient of the x-term is -3. Add the square of half of that.
.. (-3/2)² = 9/4 . . . . . . the number you need to add.
x² -3x +9/4 = (x -3/2)²
_____
If the x² term has a coefficient other than 1, you need to factor that out first and deal with the remaining binomial. For example,
.. 2x² -6x = 2(x² -3x)
For this you would need to add 9/4 inside parentheses to get
.. 2(x² -3x +9/4) = 2(x -3/2)²
Of course, to keep the original value, you would need to subtract 2*(9/4) outside parentheses.
.. 2x² -6x = 2(x -3/2)² -9/2

Answer:
to find median you add all if them together then divide it with how many numbers there are
Step-by-step explanation:
all of the equal 87 ,divide that by 10 you get 8.7 as your average
To find the answer for this question you need to first understand that 3 angles of a triangle make up 180 degrees. To make a triangle you want to cut the shape down from the 82 degrees to the degrees X. You then will be left with angle Y, a 90 degree angle, and the angle cut in half (which would be 41). You add 41 to 90 to get 131, and subtract that from 180 to get 49 degrees as your angle Y. Hope this helped <3
