$Zeros of a function - Math$

WebYou can find the zero of this function by substituting f(x) with 0 and then solving for x. 2x + 1 = 0 subtract the 1, 2x = -1, divide by 2, x = -1/2. -1/2 would be the zero of this function. WebA "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.
