Find the complex zeros of x^3+27. write f in factored form

aliina [53]

$x^3+27=0
\\x^3+3^3=0
\\(x+3)(x^2-3x+9)=0
\\x^2-3x+9=0
\\a=1,b=-3,c=9
\\
\\x_{1,2}= \frac{-b\pm \sqrt{b^2-4ac} }{2a} = \frac{-(-3)\pm \sqrt{(-3)^2-4\times1\times9} }{2\times1} =\frac{3\pm \sqrt{-27} }{2} =\frac{3\pm 3\sqrt{3}i }{2} 
\\
\\(x+3)(x-\frac{3+ 3\sqrt{3}i }{2})(x-\frac{3- 3\sqrt{3}i }{2})=0

Can anyone help with the question ! Thanks <3

Answer:

26, 42

Step-by-step explanation:

2, 4, 6, 10, 16

This sequence is $a_n=a_{n-1}+a_{n-2}$ ⇒ the next term is the sum of the previous 2 terms.

Therefore, the next 2 numbers in this sequence would be:

10 + 16 = 26 and 26 + 16 = 42
