K(k + 1)(k + 2) – 3k(k + 1)

Need a step-by-step guide on how to factor this completely

Step-by-step explanation:

k(k+1)(k+2) - 3k(k+1)

k and (k+1) are common to both terms.

k(k+1)(k+2) - 3k(k+1) = k(k+1)[(k+2) - 3] = k(k+1)(k-1)

marco saved more.   he saved $35 more.

step-by-step explanation:

1+2+3+4+5+6+7+8+9+10 = 55

2*10 = 20

55-20 = 35

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
