Can you plz i don't understand (this is for apex)

C is correct.

Explanation of what a term is:

A term is any amount of numbers and variables that are multiplied together.

In this equation, 3 - 6x - 2x² + 3x - 6x² + 2, there are six terms. 3 is a term by itself. a term can be just one number or variable. The next term is -6x. x is part of the same term as -6 because they are being multiplied together. The term after that, -2x², is a separate term from -6x by subtraction. I suppose the general idea could be that if things are being multiplied together, they are part of the same term.

Explanation of what like terms are:

Like terms are terms with the same variable and exponent.

Some examples:

The term 3 doesnt have a variable (like x) or an exponent (like ²). It can only be combined with other terms without variables and exponents. The 2 at the end doesnt have a variable or exponent either, so you can combine them. The question only asks us to put them next to each other, however.

-6x² and -2x² both have the variable x and the exponent ² in them. They can be combined. (again, the question doesnt ask to combine them yet, just to put them next to each other.)

A final note: take care to make sure that the signs (+ and -) for each term doesnt change. the 3 at the beginning is positive, so there should not be a minus symbol before it (like in the answer B).

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
