Multiplying Polynomials
Distributive Property
- Multiplying a single value to multiple terms inside a set of parentheses is possible using the distributive property.
- Formula:
a(b + c) = ab + ac - Example:
2(x + 3) = 2x + 6
Quadratic Expressions
- A quadratic expression is a polynomial of degree two, in the form
ax^2 + bx + c - Factoring quadratics involves expressing the expression as a product of two binomials
- Formula:
ax^2 + bx + c = (px + q)(rx + s) - Example:
x^2 + 5x + 6 = (x + 3)(x + 2)
Binomial Expansion
- Expanding binomials involves multiplying two binomials to form a polynomial
- Formula:
(a + b)(c + d) = ac + ad + bc + bd - Example:
(x + 2)(x + 3) = x^2 + 5x + 6
Complex Polynomial Multiplication
- Complex polynomial multiplication involves multiplying two polynomials with multiple terms
- Multiply each term in one polynomial by each term in the other polynomial
- Combine like terms to simplify the result
- Example:
(x^2 + 3x + 2)(x + 1) = x^3 + 4x^2 + 5x + 2
FOIL Method
- FOIL stands for "First, Outer, Inner, Last" and is a method for multiplying two binomials
- Multiply the:
- First terms:
a*c - Outer terms:
a*d - Inner terms:
b*c - Last terms:
b*d
- First terms:
- Combine the four terms to form the product
- Example:
(x + 3)(x + 2) = x^2 + 5x + 6
