If u(x) = x5 – x4 + x2 and v(x) = –x2, which expression is equivalent to (U divided by V) (x)
Answer:
\(\Bigg(\displaystyle\frac{u}{v}\Bigg)(x) = -x^3 + x^2-1\)
Step-by-step explanation:
We are given the following in the question:
\(u(x) = x^5 - x^4 + x^2\\v(x) = -x^2\)
We have to find the expression for:
\(\Bigg(\displaystyle\frac{u}{v}\Bigg)(x) = \frac{u(x)}{v(x)}\\\\= \frac{x^5 - x^4 + x^2}{-x^2} = -\frac{x^5}{x^2} + \frac{x^4}{x^2} - \frac{x^2}{x^2}\\\\= -x^3 + x^2-1\)
We used the property of exponents to preform this division:
\(\displaystyle\frac{a^m}{a^n} = a^{m-n}\)
The expression is equivalent to (U / V) (x) is -x³ + x² - 1.
Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers.
Here, u(x) = x⁵ - x⁴ + x²
v(x) = -x²
Now, on dividing u(x) by v(x), we get,
(u/v)(x) = \(\frac{x^5 - x^4 + x^2}{-x^2}\)
\(\frac{u}{v}(x) = \frac{x^5}{-x^2} - \frac{x^4}{-x^2}+\frac{x^2}{-x^2}\)
(u/v)(x) = -x³ + x² - 1
Thus, the expression is equivalent to (U / V) (x) is -x³ + x² - 1.
