Add/Subtract/Multiply Polynomials

Simplify (x + 5)³ .... Yes, that's to the third power. Please write your work out. So this means take (x+5)(x+5)(x + 5). Foil two binomials at a time, so this will take a few lines of work.

• x³+15x²+75x+125

• x³ + 125

• x² + 10x + 25

• x³ + 15

Simplify (2x + 3)³ .... Write down (2x + 3)(2x + 3)(2x + 3) and multiply two binomials together at a time (not all 3)

• 8x³+36x²+54x+27

• 6x³ + 27

• 8x³ + 27

• 4x² + 12x + 9

(5x⁴ – 4x³ – 2x² + x – 19) – (x⁴ + 5x³ + 8x² + x + 5)

• 4x⁴ – 9x³ – 10x² – 24

• 4x⁴ – 9x³ – 10x² – 2x – 24

• 4x⁴ – 9x³ – 10x² + 2x – 24

• -4x⁴ – 9x³ – 10x² – 24

Find the Sum: (4x - 2x³) + (5x³ - 4x + 5)

• 3x³ + 5

• 3x³ + 8x + 5

• 3x² + 5

• 7x³ + 8x + 5

Find the Sum:

(4x³ - 5x² + 3x) + (-2x³ - x² + 6x)

• 6x³ - 4x² - 3x

• -6x³ + 4x² + 3x

• -2x³ - 6x² + 9x

• 2x³ - 6x² + 9x

Find the Sum

(5x + 2) + (4x + 5)

• 9x – 7

• -9x–11

• 9x+7

(5x + 2) (x² – 3x + 6)

• 5x³ – 17x² + 24x + 12

• 5x³ + 17x² – 24x + 12

• 5x³ – 13x² + 24x + 12

• 5x³ + 13x² – 24x – 12

Find the sum.

(2x² + 5x – 7) + ( 3 – 4x² + 6x)

• 2x² + 3x +1

• -2x² – 11x – 4

• 2x² + 5x – 7

• -2x² + 11x – 4
