Solve (x–2x)²
(x-2x)²
= (-x)²
= x²
Therefore, (x-2x)² is equal to x².
Expand (x–2x)²
(x-2x)²
= (x-2x)(x-2x)
= x(x-2x) - 2x(x-2x)
= x*x - x*2x - 2x*x + 2x*2x
= x² - 2x² - 2x² + 4x²
= x² - 4x² + 4x²
= x²
Therefore, (x-2x)² expands to x².
To solve the expression (x-2x)², we need to simplify it step by step.
Step 1: Combine like terms inside the parentheses.
(x - 2x)² = (-x)²
Step 2: Simplify the expression inside the parentheses.
(-x)² = x²
Therefore, the solution to (x-2x)² is x².
