Answer:

1. 2 ( 5x - 2 )

2. 3x + 21

3. x² - x - 6

Explanation:

1.


2x + 8x - 10 + 6

Collect like terms


= 10x - 10 + 6

Calculate the sum


= 10x - 4

Factor out 2 from the expression


= 2(5x - 2)

2.


3(x + 7)

Multiply each term in the parentheses by 3


= 3x + 3 * 7

Multiply the numbers


= 3x + 21

3.


(x + 2)(x - 3)

Multiply each term in the first parentheses by each term in the second parentheses ( FOIL )


= x(x - 3) + 2(x - 3)

Calculate the product


= {x}^(2) - 3x + 2x - 2 * 3

Multiply the numbers


= {x}^(2) - 3x + 2x - 6

Collect like terms


= {x}^(2) - x - 6

Hope this helps..

best regards!!
