To determine

To calculate: The value of the expression (3x2+x+1)+(2x23x5) .

Expert Solution

Answer to Problem 15E

The value of the expression (3x2+x+1)+(2x23x5) is 5x22x4 .

Explanation of Solution

Given information:

The expression (3x2+x+1)+(2x23x5) .

Formula used:

To add or subtract two polynomials, combine all the like terms together and then perform the operation.

Calculation:

Consider the given expression (3x2+x+1)+(2x23x5) .

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,

  (3x2+x+1)+(2x23x5)=3x2+x+1+2x23x5=(3x2+2x2)+(x3x)+(15)=5x22x4

Thus, the value of the expression (3x2+x+1)+(2x23x5) is 5x22x4 .
