Answer:

the simplified expression is 13x^2 - 23x - 18.

Explanation:

To simplify the expression (3x + 2)(x - 9) + 2x(4x + 1), we can apply the distributive property and then combine like terms. Let's break it down step by step:

Step 1: Expand the expression using the distributive property.

(3x + 2)(x - 9) + 2x(4x + 1)

= (3x)(x) + (3x)(-9) + (2)(x) + (2)(-9) + (2x)(4x) + (2x)(1)

Step 2: Simplify each term.

= 3x^2 - 27x + 2x - 18 + 8x^2 + 2x

Step 3: Combine like terms.

= 3x^2 + 8x^2 + 2x^2 - 27x + 2x + 2x - 18

= 13x^2 - 23x - 18

Answer:

11x² - 23x - 15

Explanation:

(3x + 2)(x - 9) + 2x(4x + 1)

(3x + 2)(x - 9)

3x² - 27x + 2x - 18

3x² - 25x - 15

2x(4x + 1)

8x² + 2x

3x² - 25x - 15 + 8x² + 2x

11x² - 23x - 15

So, the answer is 11x² - 23x - 15
