WebThe quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√ (b²-4ac))/ (2a) . See examples of using the formula to solve a variety of equations. Created by Sal Khan.

WebAn arithmetic sequence is a sequence where each term increases by adding/subtracting some constant k. This is in contrast to a geometric sequence where each term increases by dividing/multiplying some constant k. Example: a1 = 25 a (n) = a (n-1) + 5 Hope this helps, - Convenient Colleague 1 comment ( 6 votes) Upvote Downvote Flag more Christian WebIf you have a general quadratic equation like this: ax^2+bx+c=0 ax2 + bx + c = 0 Then the formula will help you find the roots of a quadratic equation, i.e. the values of x x where this equation is solved. The quadratic formula x=\dfrac {-b\pm\sqrt {b^2-4ac}} {2a} x = 2a−b ± b2 − 4ac It may look a little scary, but you’ll get used to it quickly! fls furness lagerhaus \u0026 speditions ag
