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 ...

We need to solve a quadratic equation so we must set it equal to zero and make sure the coefficient of x 2 is positive. Rearrange the equation to get all terms on 1 side, so subtract \(x\) and ...

There’s seemingly no end to how many things you can describe with a quadratic equation. Babylonians, in particular, would solve simultaneous equations to find the roots of a quadratic.
