Number and Algebra : Module 29 Years : PDF Version of module. Coordinate geometry is one of the most important and exciting ideas of mathematics. In particular it is central to the mathematics students meet at school. It provides a connection between algebra and geometry through graphs of lines and curves. This enables geometric problems to be solved algebraically and provides geometric insights into algebra.

It is used to find the square of a binomial. This a minus b whole square formula is one of the commonly used algebraic identities. This formula is also known as the formula for the square of the difference between two terms. The a - b 2 formula is used to factorize some special types of trinomials. Let us learn more about a minus b Whole Square along with solved examples in the following section. The a - b 2 formula is also widely known as the square of the difference between the two terms. This formula is sometimes used to factorize the binomial. To find the formula of a - b 2 , we will just multiply a - b a - b. Let us consider a - b 2 as the area of a square with length a - b. In the above figure, the biggest square is shown with area a 2. In the figure above, a - b 2 is shown by the blue area. Example 1: Find the value of x - 2y 2 by using the a - b 2 formula. To find: The value of x - 2y 2. Example 3: Simplify the following using the a - b 2 formula: 7x - 4y 2. Let us understand the use of the a - b 2 formula with the help of the following example.

It is used to find the square of a binomial. EXERCISE 8 Prove that the lines joining the midpoints of opposite sides of a quadrilateral and the lines joining the midpoints of its diagonals meet in a point and bisect each other.

The calculations get longer and longer as we go, but there is some kind of pattern developing. The Binomial Theorem. An exponent of 2 means to multiply by itself see how to multiply polynomials :. Now, notice the exponents of a. They start at 3 and go down: 3, 2, 1, And now look at just the coefficients with a "1" where a coefficient wasn't shown :. They actually make Pascal's Triangle! But how do we write a formula for "find the coefficient from Pascal's Triangle" It is commonly called "n choose k" because it is how many ways to choose k elements from a set of n.

This is called the equation of the line. The following shows that this can be done given the gradient of the line and the y -intercept. Let M be the midpoint of the line AB. Notice that as you move from A to B along the interval the y -value increases as the x -value increases. Calculation Error. Gatehouse Admissions. Thank you! This formula is also known as the formula for the square of the difference between two terms. Suppose that P x 1 , y 1 and Q x 2 , y 2 are two points and let M x , y be the midpoint.
