What is a binomial expression? In Algebra, a binomial expression contains two terms joined by either addition or subtraction sign. For instance, (x + y) and (2 – x) are examples of binomial expressions.
What does a binomial expression look like?
A polynomial with two terms is called a binomial; it could look like 3x + 9. It is easy to remember binomials as bi means 2 and a binomial will have 2 terms. A classic example is the following: 3x + 4 is a binomial and is also a polynomial, 2a(a+b) 2 is also a binomial (a and b are the binomial factors).
How do you write a binomial expression?
- We will use the simple binomial a+b, but it could be any binomial.
- (a+b)2 = (a+b)(a+b) = a2 + 2ab + b2
- (a+b)3 = (a2 + 2ab + b2)(a+b) = a3 + 3a2b + 3ab2 + b3
- a3 + 3a2b + 3ab2 + b3
- Now, notice the exponents of a. ...
- Likewise the exponents of b go upwards: 0, 1, 2, 3:
