Answer:
1
Step-by-step explanation:
You "complete the square" by adding the square of half the x-term coefficient. Here, that is ...
((-2)/2)² = 1 . . . . value added to complete the square
If you want to keep 0 on the right, you must also subtract this value:
x² -2x -36 = 0
x² -2x +1 -36 -1 = 0 . . . . . . add and subtract 1 on the left
(x -1)² -37 = 0 . . . . . . . . . . . written as a square
Answer:
53

8e^(4x)×2e^(5x-1)
16e^(4x+5x-1)
When bases are same power adds.
16e^(9x-1)
Answer:
a = 3
b = -2
c = 5
Step-by-step explanation:
