Answer:
x=-16
Step-by-step explanation:
We are given with the equation

We are asked to solve it for x.
Distributing
over bracket and simplifying




Adding 8 on both sides

Dividing both sides by -3

<h3>
HCF of 4 and 9 is 1</h3>
- HCF of 4 and 9 is the largest possible number that divides 4 and 9 exactly without any remainder. The factors of 4 and 9 are 1, 2, 4 and 1, 3, 9 respectively.
So , the HCF of 4 and 9 is 1
F(x) = x^4 + 81x^2
f(x) = x^2*x^2 + x^2*81
f(x) = x^2*(x^2 + 81) ... see note 1
f(x) = x^2*(x + 9i)(x - 9i) ... see note 2
note 1: if you haven't learned about complex or imaginary numbers yet, then you would stop at the line with "note 1" on it
note 2: you would stop here if you have learned about complex or imaginary numbers and you want to factor over the complex numbers. I used the rule that
a^2 + b^2 = (a+bi)*(a-bi)
