What is the least common denominator of the rational expressions below?<br> 1/x^2 - 4/3x^2+15x
vladimir1956 [14]

Answer:

The LCD is 3x²

The other two denominators can be factors of 3x²

Step-by-step explanation:

To get the equivalent fractions, divide the original denominator into the LCD, then multiply the original numerator by the quotient.

For the first term: 1/x²

3x² ÷ x² = 3 3×1=3 The equivalent is 3/3x²

Second term: Leave it as it is.

For the third term: 15x

The implied denominator is 1

3x² ÷ 1 = 3x² 3x² × 15 = 135x²

The equivalent is 135x²/3x²

<em>To </em><em>check</em><em> </em><em>the </em><em>validity</em><em>,</em><em> </em><em>substitute</em><em> </em><em>a </em><em>value</em><em> </em><em>for</em><em> </em><em>x </em><em>and </em><em>calculate</em><em> </em><em>the</em><em> </em><em>numbers</em><em>.</em>

<em>For</em><em> </em><em>example</em><em> </em><em>let </em><em>x </em><em>=</em><em> </em><em>3</em>

<em>The </em><em>original</em><em> </em><em>expression</em><em> </em><em>becomes</em><em> </em>

<em>1/3² + 4/3(3²) - 15(3)</em>

<em>1</em><em>/</em><em>9</em><em> </em><em>+</em><em> </em><em>4</em><em>/</em><em>2</em><em>7</em><em> </em><em>-</em><em> </em><em>4</em><em>5</em>

<em>With</em><em> </em><em>the</em><em> </em><em>LCD </em><em>it </em><em>is</em>

<em>3</em><em>/</em><em>2</em><em>7</em><em> </em><em>+</em><em> </em><em>4</em><em>/</em><em>2</em><em>7</em><em> </em><em>-</em><em> </em><em>1</em><em>2</em><em>1</em><em>5</em><em>/</em><em>2</em><em>7</em>
