Question

Simplify. (x+2)(x-1)-2(x+1)​

Answer 1

x² - x - 4

Step-by-step explanation:

Multiply the parentheses

x² - x + 2x - 2 - 2 (x + 1)

Distribute -2 through the parentheses

- 2 (x + 1)

Since two opposites add up to zero, remove them from the expression

x² - x - 2 - 2

Calculate the difference

x² - x - 4

Answer 2

Answer: x²-x-4

Step-by-step explanation:

Here, we are going to use the FOIL method to simplify.

• First
• Outer
• Inner
• Last

--------------------------------------------------------------------------------------

Given

(x+2)(x-1)-2(x+1)

Expand parenthesis

= x²-x+2x-2-2x-2

Put like terms together

= x²-(x-2x+2x)-(2+2)

Combine like terms

= x²-x-4

Hope this helps!! :)
