Question 45239: I am not sure of the formula for this? Can someone help me?
Factor completely. 6x2 + 7x + 2
Below are the choices to choose from:
A( (3x + 1)(2x + 2) C) (3x – 2)(2x – 1)
B) (3x + 2)(2x + 1) D) (6x + 2)(x + 1)

You can put this solution on YOUR website! To obtain an answer for a question like this, you should take each answer they give you and multiply the terms to give the unfactored version of the polynomial. For instance, you can find out "A" is incorrect because:
(3x + 1) (2x + 2) Would equal 6x^2 + 2x + 6x + 2, which is 6x^2 + 8x + 2 (not the 6x^2 + 7x + 2 we're looking for.)
"B" Would be the correct choice because:
(3x + 2) (2x + 1) Equals 6x^2 + 4x + 3x + 2, which is 6x^2 + 7x + 2 (the answer we're looking for.)
You have to take the factored terms and multiply them out to try to equal the polynomial that you want. When you find the one that equals the polynomial, you know you have the correct answer choice.
