Are all equations in standard form? There is a standard form of linear equations – which are equations that, when graphed, form a line, and polynomial equations – which are equations in which one or both of the sides of the equation forms a polynomial. Linear equations can be described quite simply: it’s Ax + By = C, where A, B, and C are constants.
How do you verify a radical?
How do you solve two radical equations?
How do you solve a radical with a fraction? Step 1: Multiply numerator and denominator by a radical that will get rid of the radical in the numerator. If the radical in the numerator is a square root, then you multiply by a square root that will give you a perfect square under the radical when multiplied by the numerator.
