Q. What is the product of (1−p) and (21−p), all reduced by P?
Multiply binomials: First, we need to multiply the two binomials (1−p) and (21−p) together.(1−p)(21−p)=1∗(21−p)−p∗(21−p)
Distribute terms: Now, distribute the terms within the parentheses.\(1\times\left(\frac{1}{2}-p\right) - p\times\left(\frac{1}{2}-p\right) = \frac{1}{2} - p - \left(\frac{p}{2}\right) + p^2
Combine like terms: Combine like terms.21−p−2p+p2=21−23p+p2
Reduce expression by P: Now, we need to reduce this expression by P, which means we subtract P from the expression we obtained. 21−23p+p2 - P
Subtract P: Subtract P from the expression.(21−23p+p2)−P=21−23p+p2−P
Combine like terms with P: Combine P with the like terms, noting that P is the same as 1∗P or p/1. 21−23p+p2−1p=21−25p+p2
Final simplified expression: The final simplified expression is: 21−25p+p2
