Adding/Subtracting Polynomials/FOIL

Simplify
(6s² – 5s) – (–2s² + 3s)

• 7s² + 8s - 2
• 12s⁴ + 15s² 
• 8s² – 8s
• 8s⁴ 24s³

Add or subtract the polynomial below.
(8n - 3n³) - (3n³+4n)

• 24n³ -12n
• 3n³ + 6
• 4n³ - 1
• -6n³+4n

Use the FOIL method of multiplying binomials to simplify.
(x+2)(3x+1)

• 4x + 3x² +3
• 3x² - 7x +8
• 4x² + 9x + 33
• 3x² + 7x + 2

Use the FOIL Method to find the product.
(n – 5)(3n – 4)

• 4n³ - 22n + 30
• 3n² – 19n + 20
• 4n² + 19n - 20
• 3n² + 4n + 4

Simplify each product using the FOIL method.
(2h + 6)(5h – 3)

• 10h² + 24h–18
• 12h + 19h + 23
• 10h² + 2h + 18
• -10j² + 33h + 18

Simplify the product using the FOIL method.
(x + 3)(x – 5)

• x² + 8x + 15
• x² - 8x -15
• x² – 2x – 15
• 2x² + 8x + 15

Add to Simplify:
 (4x - 2x³) + (5x³ - 4x + 5)

• 3x³ + 5
• 3x³ + 8x + 5
• 3x² + 5
• 7x³ + 8x + 5

Simplify:

5(3x+2)

• 3x+10

• 15x+10

• 15x-10

• 3x-10

You can FOIL to multiply polynomials...

• When you have 2 binomials

• Any time

• When you have a monomial

• When you have only 1 binomial
