Factor the expression completely over the complex numbers. <br><br> x^3-4x^2+4x-16

Orlov [11]

First you must know that is i∧2= -1

x∧3-4x∧2+4x-16 = x∧2 (x-4) + 4 (x-4) = (x-4) (x∧2+4) = (x-4) (x∧2-(-4)) =

= (x-4) (x∧2-(-1) *4) = (x-4) (x∧2- i∧2*2∧2) = (x-4) (x∧2-(2i)∧2) = (x-4) (x-2i) (x+2i)

Good luck!!!

The formula for the area A of a triangle with base length b and height h is as follows.

vlada-n [284]

Answer:

A is given by:

$A = h^2 - 4h$

Step-by-step explanation:

The base length of the triangle is 4 units shorter than the height.

This means that $b = h - 4$

$A = bh$

$A = (h-4)h$

$A = h^2 - 4h$

The expression for A in terms of h only was given above.
