It is often the fastest way to solve a quadratic equation, so usually should be attempted before any other method. This method relies on the fact that if two expressions multiply to zero, then at least one of them must be zero. Written algebraically, this says if ab = 0, then a = 0...

In summary, to solve the given equation algebraically, one could replace sin(x) with a variable y and solve the resulting quadratic equation for y. Then, the solutions for y could be plugged back into sin(x) to obtain two goniometric equations that can be easily solved. Alternatively, one...
An unsolved problem thus far is the question of whether or not the numbers π and e are algebraically independent. This would be resolved by Schanuel's conjecture – a currently unproven generalization of the Lindemann–Weierstrass theorem. As an irrational number, π cannot be represented as a ...
An equation in a single variable may be rearranged by collecting terms in like powers to one side of the equation. If the result is a quadratic equation in standard form, then the quadratic formula may be used to find solutions.Answer and Explanation: Sta...
