(5x+6)-(-2x^2-4x+6)

Question

(5x+6)-(-2x^2-4x+6)

Answer 1

(5x + 6) - (-2x² - 4x + 6)

 

We can start by applying that negative to the numbers in the second parentheses. Also, since we're only adding/subtracting, we don't really need the parentheses around the first set, either:

5x + 6 + 2x² + 4x - 6

 

Now from here, we combine like terms.

5x + 4x = 9x

6 - 6 = 0

2x² = 2x²

 

So our final answer looks like:

2x² + 9x

 

 

Answer 2

(5x + 6) - (-2x² - 4x + 6)

 

Simplify signs by distributing the minus sign:

 

5x + 6 + 2x² + 4x - 6

 

Combine like terms:

 

2x² + 9x
