Answer:

x² + x - 2

Explanation:

Simplify the following:


\longrightarrow (x² + 2x - 1) - (x + 1)

-(x + 1) = -x - 1:

x² + 2x - 1 - x - 1

Grouping like terms,

x² + 2x - 1 - x - 1 = x² + (2x - x) + (-1 - 1):


\longrightarrow x² + (2x - x) + (-1 - 1)

2x - x = x:


\longrightarrow x² + x + (-1 - 1)

-1 - 1 = -2:


\longrightarrow x² + x - 2

Answer:

x^2+x-2

this is the answer bc the 2nd parentheses is being multiplied by the negative sign meaning you need to subtract it from the 1st parentheses.
