Show all your work multiplying the polynomials above: (You can use the FOIL or Box Method)
(x^3-4x^2+1)(3x^2+x)

3 - 11 - 4x³ + 3x² + x

Step-by-step explanation:

(x³ - 4x² + 1)(3x² + x)

Each term in the second factor is multiplied by each term in the first factor, that is

x³(3x² + x) - 4x²(3x² + x) + 1 (3x² + x) ← distribute parenthesis

= 3 + - 12 - 4x³ + 3x² + x ← collect like terms

= 3 - 11 - 4x³ + 3x² + x

the answer is 5636.7

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
