X=−1+√17 or x=−1−√17 is the answer.

First get the equation to equal 0 by subtracting 17 from both sides.
You should have x^2+2x-16=0
Next plug your numbers into the quadratic formula(-b^2+/- the square root of b^2-4ac -all divided by 2a)
The end result should be x=-1+/- the square root of 17 or(if you want the decimal) 3.12310562, -5.12310562

How to do the fractions

GaryK [48]

First you make the mixed numbers/fractions into improper fractions. After that, you must find the common denominator, the LCM of 9 and 6 (for the 2nd problem). After that, if you can, simplify the fraction to lowest terms, which also includes making it a mixed number/fraction.

I hope this helps! :)

Answer:

Hello,

Step-by-step explanation:

$2^{0} = 1$

$2^{1} = 2$

$2^{2} = 4$

$2^{3} = 8$

$2^{4} = 16$

2 x 1 = 2

2 x 2 = 4

2 x 4 = 8

2 x 8 = 16

2/1 = 4/2 = 8/4 = 16/8 = 2
