Question

Multiply (x ^ 3 + 2x - 1)(x + 4)

Answer 1

To multiply (x^3 + 2x - 1)(x + 4), we can use the distributive property and then combine like terms.

Step-by-step explanation:

To multiply (x^3 + 2x - 1)(x + 4), we can use the distributive property. We multiply each term in the first expression, (x^3 + 2x - 1), by each term in the second expression, (x + 4).

Using the distributive property, we get:

(x^3 + 2x - 1)(x + 4) = x^3(x) + x^3(4) + 2x(x) + 2x(4) - 1(x) - 1(4)

Simplifying further, we have:

x^4 + 4x^3 + 2x^2 + 8x - x - 4

Combining like terms:

x^4 + 4x^3 + 2x^2 + 7x - 4
