Factor the expression:
8x3 + 4x2 - 2x - 1
(2x + 1)(2x + 1)(2x - 1)
(2x + 1)(2x - 1)(2x - 1)
(4x + 1)(x - 1)(2x + 1)
(4x + 1)(x + 1)(2x - 1)

(2x + 1)(2x + 1)(2x - 1)

Step-by-step explanation:

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
