Question

Write this polynomial expression in its simplest form. Show your work.

Answer 1

Explanation:

(3x² + 4x - 8) - (-2x² + 4x + 2)

[3 - (-2) = 5] , [ 4 - 4 = 0] , [ (-8) - 2 = -10]

5x² + 0x - 10

(or)

5x² - 10

Answer 2

• 5x² - 6

Explanation:

Simplify

• (3x² + 4x - 8) - (-2x² + 4x + 2) =
• 3x² + 4x - 8 + 2x² - 4x - 2 =
• (3 + 2)x² + (4 - 4)x - (8 - 2) =
• 5x² + 0x - 6 =
• 5x² - 6
