Identify the expression to multiply: \(\left(5 - i\right) \times 12\).
Apply the distributive property (also known as the distributive law of multiplication over addition/subtraction) to multiply each term inside the parentheses by 12: \(5 \times 12\) and \(-i \times 12\).
Write the multiplication results as \(60\) and \(-12i\) respectively, so the expression becomes \(60 - 12i\).
Since there are no like terms to combine further, the expression \(60 - 12i\) is already simplified.
Review the result to ensure the sign and terms are correct, confirming the simplified product is \(60 - 12i\).
