Identify Like Terms: Identify the like terms in the expression.The expression is 2p−p, which contains like terms because they both have the variable p.
Combine Like Terms: Combine the like terms by subtracting their coefficients.The coefficients are 2 and 1 (since p is the same as 1p). So, 2−1=1.
Write Simplified Expression: Write the simplified expression.Since 2−1=1, the expression 2p−p simplifies to 1p, which is just p.
