Step-by-step explanation:
Given
-
=
+
Multiply through by 12 ( the LCM of 2, 3 and 4 ) to clear the fractions
18x - 6 = 4 + 3x ( subtract 3x from both sides )
15x - 6 = 4 ( add 6 to both sides )
15x = 10 ( divide both sides by 15 )
x = =
<h2>1. Pascal’s triangle</h2>
Pascal's triangle is an strategy in math that stands for a triangular array we use to solve problems of binomial coefficients. This strategy is called after the mathematician Blase Pascal. It consists in number patters. So in this problem we need to solve this following Pascal’s triangle strategy:
The strategy consists in building a triangle. So 1 is the first and last numbers in each row of Pascal’s Triangle. Next, every other number in each row is formed when you add the two numbers directly above the number, as shown in Figure below. So:
A binomial is a polynomial having two terms. So binomial expansion is a method that stands for a formula that gives us a quick method of raising a binomial to a power. So, for n=3, the binomial expansion can be written as:
