WebDescribe the steps you would use to factor 2x3 + 5x2 - 8x - 20 completely. Then state the factored form. The polynomial may have solutions which are the divisors of -20, therefore -20 has the following divisors: .If x=1, then ,if x=-1, then ,if x=2, then , then x=2 is a solution and you have the first factor (x-2). WebThe key is to “memorize” or remember the patterns involved in the formulas. Case 1: The polynomial in the form. a 3 + b 3. {a^3} + {b^3} a3 + b3 is called the sum of two cubes …
