The answer is 199.198.

Answer 2

Answer: x = {199.28959, 0.00000278768}

Step by step explanation:

0.00216140848x² - 0.43046552x + 0.0000012=0

`x = \frac{-b +/- \sqrt{b^(2)- 4ac} }{2a}`

`x = \frac{-(-0.43046552) +/- \sqrt{-0.43046552^(2)- 4(0.00216140848)(0.0000012)} }{2(0.00216140848)}`

You can do each step manually or use a quadratic calculator to do the calculations.

x = 199.28959, x = 0.00000278768
