Answer:
(x+1)(x-3i) (x+3i)
Step-by-step explanation:
x^3 + x^2 + 9x+9
We will use factor by grouping
Factor out x^2 from the first group and 9 from the second group
x^3 + x^2 + 9x+9
x^2( x+1) + 9(x+1)
Factor out (x+1)
(x+1) ((x^2+9)
Now factor x^2+9
x^2 -(3i)^2 = (x-3i) (x+3i)
Replacing this
(x+1)(x-3i) (x+3i)

Answer:
Step-by-step explanation:
For this equation: a=3, b=4, c=2
3x2+4x+2=0
Step 1: Use quadratic formula with a=3, b=4, c=2.
x= −b±√b2−4ac / 2a
x= −(4)±√(4)2−4(3)(2) / 2(3)
x= −4±√−8 / 6

No real solutions.
A cyclic quadrilateral is a quadrilateral inscribed in a circle
The measure of angle A is 106
<h3>How to determine the measure of angle A</h3>
From the question, we have:
<C= 74
Opposite angles of a cyclic quadrilateral add up to 180.
So, we have:
<A + <C = 180
This gives
<A + 74 =180
Subtract 74 from both sides
<A =106
Hence, the measure of angle A is 106
