Which expression is the factored equivalent of 3x2 + 15x + 12? A. (x + 12)(3x - 3) B. (3x + 3)(x + 4) C. (3x + 4)(x + 3) D. (x + 3)(3x - 4)

B

Step-by-step explanation:

 (3x+3)(x+4)

3x × x = 3x²

3x × 4 = 12x

3 × x = 3x

3 × 4 = 12

3x²+12x+3x+12

3x² + 15x + 12

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
