What is the standard form of the polynomial function

p(x) = 8x² + 4x + 3x⁶ + 3 ?

• p(X) = 3x⁶ + 3 + 8x² + 4x

• p(x) = 3x⁶ + 8x² + 3 + 4x

• p(x) = 3x⁶ + 8x² + 4x + 3

• p(x) = 3x⁶ + 3 + 4x + 8x²

what is the degree of the polynomial

p(x) = 20x + 14x² + 2x³

Subtract: (2a² + 5a + 3) -(a² - 3a - 4)

• 3a² + 2a - 1
• a² + 8a + 7
• 3a² + 8a + 7
• a² + 2a - 1

Find the sum.
(3x³ + 3x² – 4x + 5) + (x³ – 2x² + x – 4)

• 4x³ + 1x² – 3x + 1
• 2x³ + 1x² - 5x + 9
• 6x³ + 1x - 1x² - 3
• 3x⁵ +1x - 1x⁵ - 3x

Add to Simplify:
