## Step By Step Procedure to Find Binomial Expansion

Here, you will get the simple guidelines to solve the binomial expansion of the function. Follow these simple steps and compute the function effortlessly.

• Take any function to get the binomial expansion.
• The binomial expansion formula is given by (a+b)n = ∑ k=0 to n (n!/(n-k)! k!) an-k bk.
• Where n! = 1x2x3x4. . n.
• Substitute the expression (a+b)n to get the a, b, n values.
• Now, calculate the product for every value of k from 0 to n.
• Add those obtained expressions to get the binomial expansion.

Example

Question: Find the binomial expansion of (2x+5)3?

Given function is (2x+5)3

Binomial Expansion Formula is

(a+b)n = ∑ k=0 to n (n!/(n-k)! k!) an-k bk.

a = 2x, b = 5, n = 3.

So, (2x+5)3 = ∑ k=0 to 3 (3!/(3-k)! k!) (2x)3-k (5)k.

Calculate every value of k from 0 to 3.

For k = 0,

= (3!/(3-0)! 0!) (2x)3-0 (5)0

= 8x3

= (3!/(3-1)! 1!) (2x)3-1 (5)1

= (6/2) 4x2 * 5

= 60 x2

For k = 2,

= (3!/(3-2)! 2!) (2x)3-2 (5)2

= (6/1) (2x)1 * 25

= 150x

For k = 3,

= (3!/(3-3)! 3!) (2x)3-3 (5)3

= (2x)0 * 125 = 125

Sum up all those values

(2x+5)3 = 8x3 + 60 x2 + 150x + 125 ### FAQs on Binomial Expansion Calculator

1. What is binomial example?

Binomial is a math term having two expressions connected by a plus or minus sign. An example of binomial is x + y.

2. What is binomial expansion formula?

The formula to compute the binomial expansion is (x+y)n = ∑ k=0 to n (n!/(n-k)! k!) xn-k yk.

3. How do you define binomial expansion?

A polynomial with two terms is known as binomial. Binomial expansion of the given term is defined by the binomial theorem. A binomial theorem is a mathematical theorem which gives the expansion of a binomial when it is raised to the positive integral power.

4. Calculate the binomial expansion of (x+1)4?

(x+1)4 = ∑ k = 0 to 4 (4!/(4-k)! k!) x4-k.

= (4!/(4-0)! 0!) x4-0 + (4!/(4-1)! 1!) x4-1 + (4!/(4-2)! 2!) x4-2 + (4!/(4-3)! 3!) x4-3 + (4!/(4-4)! 4!) x4-4

= (24/24 )x4 + (24/6) x3 + (24/2*2) x2 + (24/6) x1 + (24/0) x0

(x+1)4 = x4 + 4x3 + 6x2 + 4x + 1
