How Many Roots Does The Equation X^2 + 2x + 1 = 0 Have?
How many roots does the equation x^2 + 2x + 1 = 0 have? Answer: The given equation + 2x + 1 = 0 has one root. Step-by-step explanation: To know how to answer the question correctly, here are the related details that you need to know: Roots are where polynomials are equal to zero. To compute for the roots of the given polynomial + 2x + 1 = 0, this has to be factored. How do you factor polynomials? Click the following links: brainly.ph/question/67957 , brainly.ph/question/205121 and brainly.ph/question/753406 After factoring, + 2x + 1 = 0 will become (x + 1) (x + 1) = 0. Then, set each term to zero. (x + 1) = 0 and (x + 1) = 0. Transpose the constants to the other side, and we can derive x = -1 and x = -1. This is the root of the given equation. Therefore, the equation + 2x + 1 = 0 has only one root, which is -1. That is how to solve the given question. 10.3.1.2.3.
