Question

PLEASE HELP! I WILL MARK AS BRAINLIEST!! I REALLY NEED SOMEONES HELP!

Error analysis: describe the error in the way the difference of the two polynormials is set up and/or solved. Please be specific.

(6x^2 - 5x) - (2x^2 + 3x - 2)
= 6x^2 - 5x - 2x^2 + 3x - 2
= 4x^2 - 2x - 2

Solve the problem in the question above correctly. Please show your work!

Answer 1

Since this is subtraction, everything must be turned negative in the second polynomial.

(6x^2 - 5x) - (2x^2 + 3x - 2)

6x^2 - 5x - 2x^2 - 3x - (-2)

6x^2 - 5x - 2x^2 - 3x + 2

Now, reorder the terms to make it easier.

6x^2 - 2x^2 - 5x - 3x + 2

Now, just combine like terms.

4x^2 - 5x - 3x + 2

4x^2 - 8x + 2

There’s the answer!
