Question

1. (3x + 1) (3x - 8)​

Answer 1

Step-by-step explanation:

(3x + 1) (3x - 8)

Simplifying

3x + 1 = 3x + -8

Reorder the terms:

1 + 3x = 3x + -8

Reorder the terms:

1 + 3x = -8 + 3x

Add '-3x' to each side of the equation.

1 + 3x + -3x = -8 + 3x + -3x

Combine like terms: 3x + -3x = 0

1 + 0 = -8 + 3x + -3x

1 = -8 + 3x + -3x

Combine like terms: 3x + -3x = 0

1 = -8 + 0

1 = -8

Solving

1 = -8

Answer 2

Answer:

= 3x(3x-8)+1(3x-8)

= 9x^2-24x+3x-8

= 9x^2-21x-8
