Step-by-step explanation:

We deserve to take out 2 to as this is typical in every term:

We deserve to see the the use determinants of 21 which room 1, 3, 7 and 21 (all ± values). We can use -7 and the coefficients of the simplified expression to determine if one of the values is zero once -7 is multiply and included to the coefficients:

-7> 1 7 3 21

Bring under 1

-7> 1 7 3 21

____-7_ 0_-21____

1 0 3 0

We have the right to see that the aspect of -7 yields two zeros, however the final answer is zero and therefore we deserve to use 7 factor and the answers the yielded:

We deserve to simplify the expression making use of 1, 0 and 3.

You are watching: Factor completely 2x3 + 14x2 + 6x + 42.

You space correct since everything is totally factored out

answered: ngj312

You would an initial factor out the 2 and also then use the turning back foil an approach and gain the very first answer. 2(x^2+3)(x+7)
