Express as a trinomial. (x+9)(2x-1) Answer:

Apply Distributive Property: Apply the distributive property (also known as the FOIL method) to multiply the two binomials (x+9) and (2x-1). (x+9)(2x-1) = x(2x) + x(-1) + 9(2x) + 9(-1)Multiply Binomials: Multiply each term in the first binomial by each term in the second binomial. x(2x) = 2x^2 x(-1) = -x 9(2x) = 18x 9(-1) = -9Combine Like Terms: Combine like terms. 2x^2 + (-x) + 18x + (-9) 2x^2 + 17x - 9

Q. Express as a trinomial.

\newline

(x+9)(2 x-1)

\newline

Answer:

Apply Distributive Property: Apply the distributive property (also known as the FOIL method) to multiply the two binomials $(x+9)$ and $(2x-1)$ . $(x+9)(2x-1) = x(2x) + x(-1) + 9(2x) + 9(-1)$
Multiply Binomials: Multiply each term in the first binomial by each term in the second binomial. $\newline$ $x(2x) = 2x^2$ $\newline$ $x(-1) = -x$ $\newline$ $9(2x) = 18x$ $\newline$ $9(-1) = -9$
Combine Like Terms: Combine like terms. $\newline$ $2x^2 + (-x) + 18x + (-9)$ $\newline$ $2x^2 + 17x - 9$
