B.
(2x – 3)(x – 2)

C.
(2x – 2)(x + 3)

D.
(2x – 3)(x + 2)

Answer 1

(2x+3)(x−2)

Answer 2

(2x - 3)(x + 2)

Answer 3

-3x + 2x = -x
3x - 2x = +x

Answer 4

so A?

Answer 5

B.
3x(x – 4)(x – 4)

C.
3(x + 4)(x – 4)

D.
3x(x – 4)(x + 4)

Answer 7

Answer 8

3x(x+4)(x−4)

Answer 9

It's C :)

Answer 10

3x3 – 48x

first, factor out all common factors from both terms,
we have an 'x' in both and... a 3
48 = 3 * 16

3x( x^2 - 16)

recognize that 16 is a square, its 4^2
re write the expression
(3x) (x^2 - 4^2)

looks like we have a 'difference of squres'
they look like this:
(A^2 - B^2)
= (A - B) (A + B)

can you rewrite our expressing using this method of 'differnce of squres'?
