WebUse 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 And that is the solution: x = −1/2 (You can also see this on the graph) We can also solve Quadratic Polynomials using basic algebra (read that page for an explanation). 2. By experience, or simply guesswork.
