A meeting of party members to 'choose a nominee' through debate is called a 'caucus'.

Explanation:

When the 'members' of a particular organization or a political party meet in order to discuss issues concerning and raised within the party, majorly with no external implication, it is called a caucus. In a caucus, only the issues which are prevalent within the party/organization are taken on the agenda. This kind of meetings are generally called to elect the 'leader' of the party/organization or to nominate a representative candidate on behalf of the party/organization in order to contest an election or so.

Step 1: Remove parentheses by multiplying factors.

= (x * x) + (1 * x) + (2 * x) + (2 * 1)

Step 2: Combine like terms by adding coefficients.

(x * x) = x2

(1 * x) = 1x

(2* x) = 2x

Step 3: Combine the constants.

(2 * 1) = 2

Step 4: Therefore, Simplifying Algebraic Expression is solved as

= x2 + 3x + 2.
