Question 2

Identify the degree and leading coefficient of the polynomial. 5 - 6x² + 4x

Accepted Answer

The degree of the polynomial is 2, as the highest power of x is 2. The leading coefficient is -6, which is the coefficient of the term with the highest degree, -6x^2.

Question 13

Find the special product. (3x - 9)(3x + 9)

Accepted Answer

This is an example of the difference of squares formula, $a^2 - b^2 = (a - b)(a + b)$. Here, $a = 3x$ and $b = 9$, so the product is $(3x)^2 - (9)^2 = 9x^2 - 81$.

The answer of Perform the operation and write the result...

Question 15

Multiply. (-x - 6)(-2x - 8)

Accepted Answer

To multiply the given polynomials, use the distributive property (also known as the FOIL method for binomials): (-x - 6)(-2x - 8) = (-x)(-2x) + (-x)(-8) + (-6)(-2x) + (-6)(-8) = 2x^2 + 8x + 12x + 48 = 2x^2 + 20x + 48.
