Step-by-step explanation:
<u>Roots of a polynomial</u>
If we know the roots of a polynomial, say x1,x2,x3,...,xn, we can construct the polynomial using the formula
Where a is an arbitrary constant.
We know three of the roots of the degree-5 polynomial are:
We can complete the two remaining roots by knowing the complex roots in a polynomial with real coefficients, always come paired with their conjugates. This means that the fourth and fifth roots are:
Let's build up the polynomial, assuming a=1:
Since:
Operating the last two factors:
Operating, we have the required polynomial:
Answer:
<h2>14</h2>
Step-by-step explanation:
Given the expression 3.2 + 2^3, we are to simplify and find the value of the expression.
Note that the dot means multiplication. The equation then becomes;
<em>Hence the value of the expression is 14</em>

Answer:
∠ C = 44°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
4x - 16 +6x - 1 + 4x - 13 = 180°
14x - 30 = 180 ( add 30 to both sides )
14x = 210 ( divide both sides by 14 )
x = 15
Thus
∠ C = 4x - 16 = 4(15) - 16 = 60 - 16 = 44°
