Question
Solution 1
To simplify the expression (2-7i)^2, follow these steps:
Step 1: Write down the expression (2-7i)^2
Step 2: Expand the expression using the formula (a-b)^2 = a^2 - 2ab + b^2 = (2)^2 - 2*(2)(7i) + (7i)^2
Step 3: Simplify the expression = 4 - 28i + 49i^2
Step 4: Remember that i^2 = -1 = 4 - 28i - Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
