8-(1/x)-(6/x^2)
What about it ?
find the real solutions using quadratic formula. im sorry.
For that we need an equation, you don't have one.
I will assume you meant
Solve 8 - 1/x - 6/x^2 = 0
multiply each term by x^2
8x^2 - x - 6 = 0
x = (1 ± √193)/16
To simplify the given expression, we can combine like terms.
First, let's find a common denominator for the terms involving x. The denominators are x and x^2. The common denominator is x^2 because it is the least common multiple of x and x^2.
Next, we can rewrite the expression using this common denominator:
8 - (1/x) - (6/x^2) = 8x^2/x^2 - (1/x) - (6/x^2)
Now, we can add the fractions together:
8x^2/x^2 - 1/x - 6/x^2 = (8x^2 - 1 - 6)/x^2
Simplifying further, we have:
(8x^2 - 1 - 6)/x^2 = (8x^2 - 7)/x^2
Therefore, the simplified expression is (8x^2 - 7)/x^2.
