WebJan 29, 2024 · A simple way to factorize depressed cubic polynomials of the form. (1) x 3 + A x + B = 0. Is to first move all the constants to the RHS, so ( 1) becomes. (2) x 3 + A x = − B. Now, find two factors of B such that one fact minus the square of the other factor is A. We'll call them a, b so. (3) a − b 2 = A (4) a b = − B.

WebA formula is an equation that expresses a relationship between certain quantities. A formula or equation that involves more than one variable is called a literal equation . Solve 5 a − 2 b = 15 for a . 5 a − 2 b = 15 Original equation. 5 a − 2 b + 2 b = 15 + 2 b Add 2 b to each side. 5 a = 15 + 2 b Simplify. WebHere are some main ways to find roots. 1. Basic Algebra We may be able to solve using basic algebra: Example: 2x+1 2x+1 is a linear polynomial: The graph of y = 2x+1 is a straight line It is linear so there is one root. Use 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
