Calculating the Expression (x+2)(x-7)+(x+4)(x-8)

To calculate the given expression (x+2)(x-7)+(x+4)(x-8), we can use the distributive property to expand and simplify the expression.

Expanding the expression: (x+2)(x-7) + (x+4)(x-8)

First, let's expand the terms within each set of parentheses: (x+2)(x-7) = x*x + x*(-7) + 2*x - 2*7 (x+4)(x-8) = x*x + x*(-8) + 4*x - 4*8

Now, we can simplify each expanded expression: (x+2)(x-7) = x^2 - 7x + 2x - 14 = x^2 - 5x - 14 (x+4)(x-8) = x^2 - 8x + 4x - 32 = x^2 - 4x - 32

Next, we can combine the simplified expressions: (x+2)(x-7) + (x+4)(x-8) = (x^2 - 5x - 14) + (x^2 - 4x - 32)

Now, we can combine like terms: (x^2 - 5x - 14) + (x^2 - 4x - 32) = x^2 - 5x - 14 + x^2 - 4x - 32 = 2x^2 - 9x - 46

So, the simplified form of the given expression (x+2)(x-7)+(x+4)(x-8) is 2x^2 - 9x - 46.

Final Result:

The simplified form of the given expression (x+2)(x-7)+(x+4)(x-8) is 2x^2 - 9x - 46.
