Factoring in Algebra?

3x^2 - 4x - 4
= 3x^2 + 2x - 6x - 4
= (3x^2 + 2x) - (6x + 4)
= x(3x + 2) - 2(3x + 2)
= (3x + 2)(x - 2)
(answer A)

16z^2-40z+25 a million. locate the climate of the 1st and 0.33 words (16z^2 and 25) (yet for the 0.33 term u basically want 0.5 of them) ----components---- sixteen a million 5 5 a million sixteen 25 a million <--u do not choose a million 25 (basically 0.5 mandatory) 4 4 2 8 8 2 2.multiply the climate of the 1st term with the 0.33 (outer x outer, inner x inner) so as that it equals the middle term Ex: sixteen a million 5 5 ---> sixteen x 5 a million x 5 -----> 80 5 3. the polynomial u have has a - and then a +, which skill the two words could be subtraction interior the respond. Ex: (16z- )(z- ) ----> nonetheless it is not finished or splendid, be conscious that the two the operations interior the parenthesis are subtraction. (if the two are effective interior the polynomial, then the two could be addition interior the respond.) 4. multiply the climate which may well be 4 4 5 5 ---> 20 + 20= forty 5. positioned them interior the parenthesis. (4z-5)(4z-5) (be conscious the 1st words pass in first and the 2d pass in 2d) 6. your carried out! yay! :D FOIL if u choose to examine your answer

The answer is: (3x + 2)(x - 2)
Letter A

(3x + 2)(x - 2)
OPTION A

3x² - 4x - 4 = (3x + 2)(x - 2)

Answer
A. (3x + 2)(x - 2)

A

Answer A. (3x+2)(x-2)

A

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

well..it goes like this..:)
3x^2 - 4x - 4 = ( 3x + 2 ) ( x - 2 )
so..it would be (A)! =)

hope i was of some help! all the best! :0)

The answer is A, though I cannot tell what the question marks are supposed to be. None of B or C or D can be factors of the original equation -- no matter what operator replaces the ?.
