Studdy Solution

STEP 1

1. We are given a polynomial expression in the form of a fraction.
2. The goal is to simplify the expression by performing polynomial division.
3. The division involves dividing each term in the numerator by the term in the denominator.

STEP 2

1. Identify and separate each term in the numerator.
2. Divide each term in the numerator by the term in the denominator.
3. Simplify each resulting term.

STEP 3

Identify the terms in the numerator:
The numerator is 4.5x2+3.6x-4.5x^2 + 3.6x.

STEP 4

Divide each term in the numerator by the denominator 0.5x0.5x.
First term: 4.5x20.5x \frac{-4.5x^2}{0.5x}
Second term: 3.6x0.5x \frac{3.6x}{0.5x}

STEP 5

Simplify each resulting term.
First term: 4.5x20.5x=4.50.5×x2x=9x \frac{-4.5x^2}{0.5x} = \frac{-4.5}{0.5} \times \frac{x^2}{x} = -9x
Second term: 3.6x0.5x=3.60.5×xx=7.2 \frac{3.6x}{0.5x} = \frac{3.6}{0.5} \times \frac{x}{x} = 7.2
Combine the simplified terms:
9x+7.2 -9x + 7.2
The simplified expression is:
9x+7.2 \boxed{-9x + 7.2}
