Your equation is: x^3-4x^2-5x+20 divide this equation by (x-4) to get: (x-4) * (x^2-5) This factors out to: (x-4) * (x-sqrt(5)) * (x+sqrt(5)) I confirmed it's accurate by replacing x with 5 in both the original equation and the factored equation to get the same answer. For these trinomials, we can factor by grouping by dividing the x term into the sum of two terms, factoring each portion of the expression separately, and then factoring out the GCF of the entire expression. If you are factoring a quadratic like x^2+5x+4 you want to find two numbers that Add up to 5 Multiply together to get 4 Since 1 and 4 add up to 5 and multiply together to get 4, we can factor it like: (x+1)(x+4) Current calculator limitations.
