Find the complex zeros of the following polynomial function.

Mathematics
1 answer:
GalinKa [24]2 years ago
6 0

Answer:

x=\frac{-1\pm\sqrt{3}i}{2}

Step-by-step explanation:

f(x)=x^3-1

0=x^3-1

0=(x^2+2x+1)(x-1)

x-1=0

x=1 <-- Real Solution

x^2+x+1=0

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

x=\frac{-2\pm\sqrt{2^2-4(1)(1)}}{2(1)}

x=\frac{-1\pm\sqrt{1^2-4(1)(1)}}{2(1)}

x=\frac{-1\pm\sqrt{1-4}}{2}

x=\frac{-1\pm\sqrt{-3}}{2}

x=\frac{-1\pm\sqrt{3}i}{2} <-- Complex Solutions

2b plus 4a minus a minus 2 plus 12b
jarptica [38.1K]

The value of the expression 2b plus 4a minus a minus 2 plus 12b is 3a + 14b - 2.

Expression:

An expression is defined as the a combination of operators, constants and variables. And it may consist of one or more operands, and zero or more operators to produce a value.

Given,

Here we have the statement "2b plus 4a minus a minus 2 plus 12b".

Now, we have to find the simplified form of this statement.

In order to find the simplified form,

First we have to convert the statement into expression form, then we get

2b plus 4a minus a minus 2 plus 12b = 2b + 4a - a - 2 + 12b

Now, we have to combine the like terms, then we get,

=> (2b + 12b) + (4a - a) - 2

Perform the appropriate arithmetic operations, then we get the simplified form of the expression as,

=> 14b + 3a - 2

Now, we have to arrange them in order then we get,

=> 3a + 14b - 2

maria [59]
8x + 3× + 9x = 180

20x = 180
x = 180/20
x = 9

The smallest angle is: 3×9 = 27 degrees

Note: 180 degrees is the sum of angles in a triangle
