Answer:

Option A

Step-by-step explanation:

Given function is,

$f(x)=x^4-x^2-6$

Hint: $(-1=-3+2)$ and $(-3)(2)=-6$

$f(x)=x^4-3x^2+2x^2-6$

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

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

$f(x)=(x^2+2)(x^2-3)$ is the factored form of the given function.

Option A will be the correct option.

3x+8=5x-20<br><br>what is x ?

Minchanka [31]

First you need to get x on one side so subtract 3x from both sides which will leave you with 8=2x-20. Next add 20 to both sides to get 28=2x. Then divide everything by 2 and you should get x = 14.
