Question

(2x - y + 3) (2x - y - 3)​

Answer 1

Answer:

Step-by-step explanation:

: step 1

1.1     Evaluate : $(2x+y)3 = 8x3+12x2y+6xy2+y3$

1.2     Evaluate :  $(2x-y)3 = 8x3-12x2y+6xy2-y3$

STEP

2

Pulling out like terms

2.1     Pull out like factors :

$16x3 + 12xy2 = 4x • (4x2 + 3y2)$

final answer:

$\\ 4x • (4x2 + 3y2)$
