Which product of prime polynomials is equivalent to 3x^4 - 81x? a) 3x(x − 3)(x2 – 3x - 9)
b) 3x(x − 3)(x2 + 3x + 9)
c) 3x(x - 3)(x - 3)(x + 3)
d) 3x(x − 3)(x + 3)(x + 3)

b)

Step-by-step explanation:)

Take a factor from the expression. You're left with which is a difference of cubes. Cube differences are decomposed as a product as (an easy way to remember that is that you already have the minus in the first bracket to cancel out terms, so they're all pluses in the second).

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
