Question

Simplify the following polynomial and write the answer in standard form. (2x^2-4x+3) + (x^2-4x-4)​

Answer 1

3x^2 - 8x - 1

Explanation:

(2x^2-4x+3) + (x^2-4x-4)​

First you take off the brackets:

2x^2-4x+3 + x^2-4x-4

Then combine the like terms:

2x^2 + x^2 = 3x^2

-4x - 4x = -8x

3 - 4 = -1

And finally write in Standard form (largest to smallest value):

3x^2 - 8x - 1
