What is the factored form of this expression? x^3-6x^2-9x+54

Nesterboy [21]

The factored form of this expression is (x+3)(x-3)(x-6)

<h3>Factored form of an expression</h3>

Given the polynomial function

x^3-6x^2-9x+54

Group

(x^3-6x^2)-(9x+54)

Factor out the greatest common factor

x^2(x-6) - 9(x- 6)

Find the factors

(x^2-9)(x-6)

using the difference of two square

(x+3)(x-3)(x-6)

Hence the factored form of this expression is (x+3)(x-3)(x-6)

What are the values that satisfy the trigonometric equation for: 0≤q≤2π ?<br> sin(∅)+tan(−∅)

Mrac [35]

Answer:

First choice: 0, pi

Step-by-step explanation:

I am assuming the equation is

$\sin q + \tan (-q) = 0$

(the =0 part is missing in the original problem)

$\sin q + \tan (-q) = 0\\\sin q + \frac{\sin (-q) }{\cos (-q)} = 0\\\sin q + \frac{-\sin q}{\cos q}=0\\\sin q = \frac{\sin q}{\cos q}\\\sin q \cdot \cos q = \sin q\,\,,\,\,\, 0\leq q \leq 2\pi\\\implies\\\cos q = 1 \implies q=\{0, 2\pi\}\\\mbox{or}\\\sin q = 0 \implies q=\{0, \pi, 2\pi\}\\\implies\\q=\{0,\pi,2\pi\}$
