\(y = x + 3\) is a linear equation and \(y = x^2 + 3x\) is a quadratic equation. If the product of two numbers is zero, then one or both numbers must also be equal to zero. To solve, put each ...

There are no straight-line segments on a quadratic graph. The coordinates \((x, y)\) are plotted and joined by drawing a freehand curve. Two consecutive ... each term in the equation to work ...
