Which expressions are equivalent to 3x + 2(x − 1) − 4? a.) 3x + 2x - 2 - 4 b.) 5x - 6 c.) 3(x - 4) d.) 3(x + 2) - 6 e.) 6(x - 1)

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

answer: f true
