Answer to Problem 19E
The value of the expression
Explanation of Solution
Given information:
The expression
Formula used:
To multiply the polynomials or algebraic expressions apply the distributive property which is expressed as
To add or subtract two polynomials, combine all the like terms together and then perform the operation.
Calculation:
Consider the given expression
Recall that to multiply the polynomials or algebraic expressions apply the distributive property which is expressed as
Apply it,
Recall that to add or subtract two polynomials, combine all the like terms together and then perform the operation.
Apply it,
So, the value of the expression will be calculated as,
Thus, the value of the expression
