3x3-27x=0<br> Solve by factoring a

Eddi Din [679]

After factoring $3x^3-27x=0$ the solutions are x=0 , x=3, x= -3

Step-by-step explanation:

We need to solve by factoring:

$3x^3-27x=0$

Solving:

$3x^3-27x=0$

Taking 3x common:

$3x(x^2-9)=0$

Now using formula $a^2-b^2=(a-b)(a+b)$

$3x((x)^2-(3)^2)=0\\3x(x-3)(x+3)=0$

$3x=0\,\,and\,\,x+3=0\,\,and\,\,x-3=0\\x=0\,\,and\,\,x=-3\,\,and\,\,x=3\\$

So, After factoring $3x^3-27x=0$ the solutions are x=0 , x=3, x= -3

Answer:

g(x)= 1/4 |x-2| + 1

Step-by-step explanation:

line:

g(x)

points on same line:

(2, 1) and (6, 2)

slope based on the points

m= (2-1)/(6-2)= 1/4

And the line is moved to the right by 2 units:

So the function becomes:

g(x)= 1/4|x-2|

Considering movement up by 1 unit as well:

g(x)= 1/4 |x-2| + 1

This is the final of equation for the line.
