Answer 2

Calculating the Expression -2x(x-a)+(8-x)(8+x)

To calculate the expression -2x(x-a)+(8-x)(8+x), we can start by simplifying the expression step by step.

First, let's expand the expression and combine like terms:

Step 1: Expand the expression -2x(x-a)+(8-x)(8+x) -2x(x-a) + (8-x)(8+x) = -2x^2 + 2ax + 64 + 8x - x^2 = -2x^2 - x^2 + 2ax + 8x + 64

Step 2: Combine like terms = -3x^2 + 2ax + 8x + 64

So, the simplified expression is -3x^2 + (2a+8)x + 64.

This is the simplified form of the given expression.
