Factor the polynomial function over the complex numbers. f(x)=x^3-2x^2+3x-6

Airida [17]

$f(x)=x^3-2x^2+3x-6=x^2(x-2)+3(x-2)=(x-2)(x^2+3)\\\\i=\sqrt{-1}\to i^2=-1\\\\x^2+3=x^2-(-3)=x^2-3i^2=x^2-(\sqrt3)^2i^2)=x^2-(i\sqrt3)^2\\\\\text{use}\ a^2-b^2=(a-b)(a+b)\\\\\boxed{f(x)=(x-2)(x-i\sqrt3)(x+i\sqrt3)}$

Can u guys help me with these two problems?? for the first one I got 76 ,but I don't think is right.

Elina [12.6K]

Answer:

See below

Step-by-step explanation:

15)

In the right-angle triangle, once one of the angles is 44º, then, the unknown angle is $x$ .

$180 = 44 + 90 + x$

$180 = 134 + x$

$x= 46$

The angle $y$ of the other triangle plus the angle $x$ of the right-angle triangle is equal to 90º, therefore they are complementary angles.

So,

$90 = x + y$

$90 = 46 + y$

$y=44$

To find ?, we have

$180 = 58 + 44 +?$

$? =78$

16)

The sum of the internal angles of the triangle with angles 50º and 25º is equal to 180º, therefore, the other angle is

$180 = x + 50 + 25\\180 = x+ 75\\x=105$

Once the angles are opposite, they are the same. For the triangle with the 36º angle, we have

$180 = 36 + 105 + y$

$180 = 141+ y$

$y=39$

$?=39$

I need help!!!! Please

Veronika [31]

1x100,000 = 100,000
3x10,000 = 30,000
9x1,000 = 9,000
8x100 = 800
5x10 = 50
2x1 = 2
Add these all together to get your answer. Standard form is the form we usual write numbers in.
