A. - 2x2 +2x b. 2x2-2x-8 c. 2x2 - 2x-8 d. - 2x2 +2x-8

Answer 1

Given:

Two expressions:

• (-6x + 4x² - 4)
• (-8x + 4 + 6x²)

What To Do:

We have to subtract and find the difference.

Solution:

(-6x + 4x² - 4) - (-8x + 4 + 6x²)

Remove the brackets,

⇒ -6x + 4x² - 4 + 8x - 4 - 6x²

Rearrange the like terms,

⇒ 4x² - 6x² - 6x + 8x - 4 - 4

Solve the first term,

⇒ -2x² - 6x + 8x - 4 - 4

Solve the second term,

⇒ -2x² + 2x - 4 - 4

Solve the third term,

⇒ -2x² + 2x - 8

∴ Hence the difference of the expression is -2x² + 2x - 8.
