Adding Subtracting Multiplying Multiple Polynomials

Subtract the following polynomials: (-5x² + x³ - 2x + 3) - (-5x² -x³ + 4x + 8)

• 2x³ - 6x + 11

• 2x³ - 6x - 5

• 2x³ - 10x² - 6x - 5

• - 10x² - 6x - 5

(4x+1)(5x−2)

• 20x² + 3x − 2

• 20x² − 11x + 5

• 20x² − 18x + 2

• 20x² − 3x − 2

Simplify.

(5h - 3)(3h+7)

• 15h² -44h +21

• 15h² +44h -21

• 15h² -26h +21

• 15h² +26h -21

Simplify.

2n (n² + 3n + 4)

• 2n³ + 6n² + 8n

• 2n³ + 6n + 8

• 2n³ + 3n + 4

• n² + 5n + 4

Simplify.

(b + 3) (b² + 2b + 1)

• b³+ 6b²+ 6b + 3

• 4b³ + 8b² + 3b

• b³ + 5b² + 7b + 3

• 3b³ + 6b² + 3b

When polynomials are added or subtracted, the coefficients of the terms with the same power of the variable are added or subtracted. (combining like terms)
