Write a trinomial that has (2x + 1) as a factor. ?

Question

i have no clue how to do this

Answer 1

(2x+1)^3

Answer 2

A trinomial is a polynomial with three terms.  Since (2x+1) must be a factor of your trinomial, the easiest way to answer is just to multiply the binomial (2x+1) by some other binomial, e.g.:

(2x+1)(x+1) = 2x^2 + 3x +1

Answer 3

Just use another element like the one you were given.  

(4x -1)

(8x +3)

(12x+5)

ANYTHING you choose. MAKE SURE THERE'S ONLY ONE VARIABLE WITHIN

Multiply them out and you"ll have a trinomial.  in rare cases you might do a perfect square or somthing but 99% of the times, you'll get a trinomial.

(12x +5)(2x +1)

24x^2 +12x + 10x +5

24x^2 + 22x +5 BAM your trinomial

(2x+1)(2x-1)

4x^2 - 2x +2x -1

4x^2 -1 BONG sorry this is a perfect square
