Chapter 5: Q. 26 (page 498)

In the following exercises, add or subtract the monomials.
$2 a^{2} + b^{2} - 6 a^{2} + x^{2} y - 3 x + 7 x y^{2}$

Short Answer

Expert verified

The required result is $2 a^{2} + b^{2} - 6 a^{2} + x^{2} y - 3 x + 7 x y^{2} = - 4 a^{2} + b^{2} + x^{2} y - 3 x + 7 x y^{2}$

Step by step solution

Step 1. Given information

$\begin{array}{l} Thegivenexpressionis \\ 2 a^{2} + b^{2} - 6 a^{2} + x^{2} y - 3 x + 7 x y^{2} \\ Wehavetoaddorsubtractasapplicable. \end{array}$

Step 2. Simplify

$\begin{array}{l} Considerthegivenexpression \\ \Rightarrow 2 a^{2} + b^{2} - 6 a^{2} + x^{2} y - 3 x + 7 x y^{2} \\ = 2 a^{2} - 6 a^{2} + b^{2} + x^{2} y - 3 x + 7 x y^{2} [Combinetheliketerms] \\ = (2 - 6) a^{2} + b^{2} + x^{2} y - 3 x + 7 x y^{2} [Simplify] \\ = - 4 a^{2} + b^{2} + x^{2} y - 3 x + 7 x y^{2} \end{array}$
