PROJECT 1 For project #1 we are to solve equations (a) and (c) using all 6 steps listed in the example. The basis of this project actually comes from an interesting method for solving quadratic equations. This method originated from India. Below is the list for the step by step instructions I used from the method derived in India to solve equations (a) : x2-2x-13=0 and (c) : x2+12x-64=0 1. Move the constant term to the right side of the equation

HCF‚ let’s understand What is Prime number? Consider this number : 12. This number can be found in many multiplication tables for example 1 x 12=12. 2 x 6 =12 3 x 4=12 That means‚ 12 has many factors (1‚2‚3‚4‚6‚12). Such number is called a composite number. On the other hand‚ consider this number: 29. You cannot find it in any table except 29 x 1 =29. Such number is called a prime number. Let’s make a shortlist from exam point of view Prime Non-prime (composite) 2‚3‚5‚7‚11‚13‚17‚19‚23

Find the prime factorization of the two numbers. 2 66 3 33 11 11 1 2 28 2 14 7 7 1 28 = 22 x 7 66 = 2 x 3 x 11 Any multiple of 66 will also have 2‚ 3 and 11 as its factors. Likewise any multiple of 28 well have 2 and 7 as its factors. The common multiple will have all the prime factors of the two numbers as its factors.
