Find the roots of an equation
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. WebIf a quadratic equation can be factorised, the factors can be used to find the roots of the equation. The equation factorises to give \((x – 3)(x – 3) = 0\) so there is just one solution to ...
