Answer:
Option D, 5 plus i square root of 11
Step-by-step explanation:
We have to find the solution of x² - 10x = -36
x² - 10x = -36
x² - 10x + 36 = 0
x² - 2(5x) + 25 + 11 = 0
(x-5)² + 11 = 0
(x-5)² = -11
(x-5) = √(-11)
x = 5 + i√11 [ since √(-1) = i]
Option D 5 plus i square root of 11 is the answer.
I know that this is an old question, but I'll add my input for future reference. The graph shown above is B) This is a function (as it passes the vertical line test), but it is NOT a one-to-one, as it fails the horizontal line test.
