Find the roots of factored polynomials

Full solution

Q. Rewrite in simplest terms:

0.4(3 k+4 k+9)-0.3 k

\newline

Answer:

Distribute and Multiply: First, distribute $0.4$ to each term inside the parentheses. $\newline$ $0.4 \times 3k + 0.4 \times 4k + 0.4 \times 9$
Perform Multiplication: Now, perform the multiplication for each term. $\newline$ $1.2k + 1.6k + 3.6$
Combine Like Terms: Combine like terms $1.2k$ and $1.6k$ . $1.2k + 1.6k = 2.8k$
Rewrite Expression: Now, rewrite the expression with the combined like terms. $2.8k + 3.6 - 0.3k$
Subtract and Combine: Subtract $0.3k$ from $2.8k$ to combine the $k$ terms. $\newline$ $2.8k - 0.3k = 2.5k$
Write Simplified Expression: Finally, write down the simplified expression. $2.5k + 3.6$
