Question

Subtract these polynomials (3x^2 + 3x + 3) - (x^2 + 2x + 3)= A. 2x^2 + 5x + 6 B. 2x^2+x+6

Answer 1

B. 2x^2 + x + 6 is correct from the question

Answer 2

Answer: 2x² - x

Explanation:

Our task is to subtract these polynomials:

`\sf{(3x^2+3x+3)-(x^2+2x+3)}`

Distribute the minus:

`\sf{3x^2+3x+3-x^2-2x-3}`

Combine like terms:

`\sf{3x^2-x^2+3x-2x+3-3}`

`\sf{2x^2-x}`

Answer: 2x² - x
