Verifying Solutions Brilliant Math & Science Wik

Verifying solutions is a good way to double-check the work on any problem. Sometimes it is an essential step to obtaining the correct solution, such as when working with radical equations or completing the square to solve a problem, which may result in an extraneous root. x + 7 = 10. x+7=10 x+ 7 = 10 The process of making sure a solution is correct by making sure it satisfies any and all equations and/or inequalities in a problem. 1 Example: Verify that x = 3 is a solution of the equation x 2 - 5 x + 6 = 0. To do this, substitute x = 3 into the equation Plug the solution back into the equation. This is the simplest way to check that your answer is correct. If you solved for a variable or multiple variables, plug these solutions back into the equation and work backwards to see if they make the equation true Thanks for contributing an answer to Stack Overflow!

You should always check that your solution really is a solution. How To Check. Take the solution(s) and put them in the original equation to see if they really work. Example: solve for x: 2xx − 3 + 3 = 6x − 3 (x≠3) We have said x≠3 to avoid a division by zero. Let's multiply. The College Board has very careful and systematic quality control processes to ensure accuracy of your test score. If you would like to double-check your scores, you have access to score verification services. Answer Services An answer verification service is available for every SAT administration.

Regular expression: Require text answers to match certain formulas that you choose. Learn more about regular expressions Now that you know 16(20) is congruent to 1 mod 29, multiply both sides of the equation by 5 to get 100(16), a congruent to modulo 29. And because 100 is congruent to 13 mod 29, the solution to the linear congruence 16x = 5 modulo 29 is 13. Lastly, verify that 16(13)-5 will leave a zero remainder when you divide it by 29 After you create your course, you need to give students your course ID (generated by Pearson MyLab), which they'll use to enroll in your MyLab Math course.
