Steps to factor 12x^3-9x^2+8x-6by

  the polynomial cannot be factored

Step-by-step explanation:

The ratios of coefficients are 4:3 in the first and second pairs of terms, but the similarity ends there. The second pair of terms has no common factor but 2, and factoring that out leaves nothing in common with the rest of the expression:

  = 3x^2(4x -3) +2(4x -3by)

If by=1, this would factor nicely as (3x^2 +2)(4x -3), but that is not the case. The "by" term effectively makes the expression unfactorable.

The expression cannot be factored.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

i got 10.28 but that rounds up to 10.3
