Which of the expressions below have exactly 3 terms? Select all that apply. A) 10x + 8
B) 3x3 + 6x2 + 9x + 12
C) 6x + 9–3x2
D) 833 + 12x + 16

C. 6x + 9 - 3x^2

Step-by-step explanation:

We have 4 expressions and are being asked which has 3 terms.

When it comes to terms, terms are numbers that are different, it could be separated through a variable, square root, symbol, e.t.c.

So when looking for an answer, we need 3 numbers with different variables or symbols, let's look

A. only has two, 10x and 8. Therefore it is wrong.

B. has 4 terms, 3x^3, 6x^2, 9x, and 12. Therefore it is wrong.

C. is correct because it has 3 terms, 6x, 9, and 3x^2.

D. has 2 terms, 833 and 12x, though 16 is there, it is the same as 833, therefore not counting it as its own term.

the square root of 16 is 4.

4*4 = 16
