Using PDF Editors and Generators
Tools like Adobe Acrobat, Canva, or online worksheet generators can help you compile problems and answers into a professional PDF document.
Sample Problems and Solutions
To illustrate the usefulness of these worksheets, here are sample problems with solutions:
Problem 1: Multiply \( (3x + 4) \) by \( (x - 2) \).
Solution:
Using the distributive property:
\[ (3x + 4)(x - 2) = 3x \times x + 3x \times (-2) + 4 \times x + 4 \times (-2) \]
\[ = 3x^2 - 6x + 4x - 8 \]
Combine like terms:
\[ 3x^2 - 2x - 8 \]
Problem 2: Multiply \( (x^2 + 5x + 6) \) by \( (x + 4) \).
Solution:
Distribute each term:
\[ x^2 \times x + x^2 \times 4 + 5x \times x + 5x \times 4 + 6 \times x + 6 \times 4 \]
\[ = x^3 + 4x^2 + 5x^2 + 20x + 6x + 24 \]
Combine like terms:
\[ x^3 + (4x^2 + 5x^2) + (20x + 6x) + 24 \]
\[ = x^3 + 9x^2 + 26x + 24 \]
