The volume (in cubic meters), v, of a rectangular room is given by the expression:
yan [13]

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.

The product of two consecutive integers is 56.find the the integers.
defon

Let, the integers = x,(x+1)

x*(x+1) = 56

x²+x = 56

x²+x-56 = 0

x²+8x-7x-56=0

x(x+8)-7(x+8)=0

x+8= 0  OR x-7=0

x = -8 OR x = 7

it would be -8 & -7 or 7 & 8
