Answer:

  7(b^2 -2)(b^2 +2)

Step-by-step explanation:

Factoring the common factor 7 from both terms, you get the difference of squares. That can also be factored.

  v = 7(b^4 -4) = 7(b^2 -2)(b^2 +2)

The difference b^2-2 will have irrational factors, so does not meet the problem requirements. This is the factorization over integers.

I don’t understand how to factor trinomials
gayaneshka [121]
When the X term is one, and doesn't have a leading coefficient, then you can factor it using the box and diamond method. look up videos on Khan Academy of the box and diamond method for solving trinomials. For number 9, you have a difference of squares. That means you can factor to just 2 terms. (x+4)(x-4) this works because 16 has an easy square root, and the sign in between is a negative(difference)
