Answer: Option C
Step-by-step explanation:
the blue tiles are positive, and the red ones are negative.
The upper ones are a number and the lower ones are other, so the equations that we have are:
upper: x^2 + 4x - 2
lower: x^2 - 2x + 4
so this can be written as:
then we have:
upper + lower = (x^2 + 4x - 2) + (x^2 - 2x + 4) = 2x^2 + 2x + 2
Then the correct option is C, while this is written as:
(x^2 + 4x - 2) - (-x^2 + 2x - 4) = 2x^2 + 2x + 2
Where you can distribute the minus sign with the second parentheses, and get our previous equation.
