Factor (3x+2)(3x^2-6x+4)

Answers

Answer:

(3x+2)(3x-2)(x-2)

Step-by-step explanation:

1. you do trinomial factoring for the second factor (the one with three terms)

2. you put a 3x in one parentheses and an x in the other and find all the numbers that make positive 4.

3. Now foil (first,outside,inside,last) and see which ones match the factor above

4. You should be left with three factors at the end.

How do you do that plz help or just give the answer

Answers

2x-(-1/2x-1/2)=8
the - sign before the first parentheses is a negative 1
you distribute the -1 into the parentheses
-1 multiplied by -1/2x is 1/2x and -1 multiplied by -1/2 is 1/2.
so now we have 2x-1/2x+1/2=8
you combine like terms (2x and -1/2x)
you get 1 1/2x+1/2=8
you subtract the 1/2 to get 1 1/2x= 7 1/2
you divide everything by 1 1/2.
the answer is x=5
