Q. Evaluate p2−5\frac{p}{2}-5 when p=14p=14.
  1. Substitute given value: Substitute the given value of pp into the expression.\newlineGiven p=14p = 14, substitute it into the expression p2−5\frac{p}{2} - 5.\newlineExpression: (142)−5\left(\frac{14}{2}\right) - 5
  2. Simplify division: Simplify the division part of the expression.\newlineDivide 1414 by 22.\newline142=7\frac{14}{2} = 7
  3. Subtract 55: Subtract 55 from the result of the division.\newlineNow take the result from the previous step and subtract 55.\newline7−5=27 - 5 = 2
