WebHere are some main ways to find roots. 1. Basic Algebra We may be able to solve using basic algebra: Example: 2x+1 2x+1 is a linear polynomial: The graph of y = 2x+1 is a straight line It is linear so there is one root. Use Algebra to solve: A "root" is when y is zero: 2x+1 = 0 Subtract 1 from both sides: 2x = −1 Divide both sides by 2: x = −1/2 WebGain more insight into the quadratic formula and how it is used in quadratic equations.
