Answer:
- y = (x - 4)(x + 2i)(x - 2i)(x + √3)(x - √3) Possible answer
- y = (x - 4)(x^2 + 4)(x^2 - 3) Possible answer
Step-by-step explanation:
The simplest answer is that 2i cannot be a lone root. It must have a twin that is - 2i
√3 has the same sort of rule. It cannot be a root all by itself. It also must have a twin, in this case -√3
So the answer must be
(x - 4)(x + 2i)(x - 2i)(x + √3)(x - √3) <<< Possible answer
but this can be reduced even further.
- (x + 2i)(x - 2i) = x^2 - x*2i + x*2i - 4i^2
- (x + 2i)(x - 2i) = x^2 - 4(i)^2
- (x + 2i)(x - 2i) = x^2 + 4. Remember i^2 = - 1
By a similar method (x - √3)(x + √3) = x^2 - 3
So the polynomial is reduced to
(x - 4)(x^2 + 4)(x^2 - 3) <<<< Answer
If this is not among your answers and the factored form is not either, please tell me what is.
The angles inside a trapezoid add up to equal 360 degrees
X = 360-90-90-75 = 105 degrees.
Hello!
You can draw this out and count the squares
When you do this you get 24 squares
The answer is 24 square units
Hope this helps!
There are 8 tens in the number 1,384.
Each digit in the number has an equivalent value based on its placement in the number.
1,384 where:
1 is in the thousands value
3 is in the hundreds value
8 is in the tens value
4 is in the ones value
The extended form of 1,384 is:
1 x 1000 + 3 x 100 + 8 x 10 + 4 x 1 = 1,384
1,000 + 300 + 80 + 4 = 1,384
8 x 10 = 80 ; shows that there are 8 10s in the number with a product of 80.
