Chapter 5: Q. 51 (page 498)

In the following exercises, find the difference of the polynomials.
Find the difference of $(w^{2} + w - 42)$ and $(w^{2} - 10 w + 24)$

Short Answer

Expert verified

$Thedifferenceof (w^{2} + w - 42) and (w^{2} - 10 w + 24) is 11 w - 66.$

Step by step solution

Step 1. Given information

$\begin{array}{l} Thegivenexpressionsare \\ (w^{2} + w - 42) and (w^{2} - 10 w + 24) \\ Wehavetofindthedifference \\ i . e Tofind: (w^{2} + w - 42) - (w^{2} - 10 w + 24) \end{array}$

Step 2. Calculating the difference

$\begin{array}{l} \Rightarrow (w^{2} + w - 42) - (w^{2} - 10 w + 24) \\ = w^{2} + w - 42 - w^{2} + 10 w - 24 [Rewritewithoutparentheses] \\ = w^{2} - w^{2} + w + 10 w - 42 - 24 [Combinetheliketerms] \\ = 11 w - 66 [Simplify] \end{array}$
