Learn how to solve simplify trigonometric expressions problems step by step online. x^2+2x+1=0 . Math interpretation of the question. To find the roots of a polynomial of the form ax^2+bx+c we use the quadratic formula, where in this case a=1, b=2 and c=1. Then substitute the values of the coefficients of the equation in the quadratic formula: \displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}. Simplifying. To obtain the two solutions, divide the equation in two equations, one when \pm is positive (+), and another when \pm is negative (-).

Final Answer

$x=-1,\:x=-1$
