Identify common factors: Identify common factors.Look for the greatest common factor (GCF) that can be factored out from all terms in the polynomial 4x−2x2−2x3.The GCF is 2x, as each term is divisible by 2x.
Factor out the GCF: Factor out the GCF.Factor out the GCF, 2x, from each term in the polynomial.2x(2−x−x2)
Rearrange terms in parentheses: Rearrange the terms in the parentheses.Rearrange the terms inside the parentheses in descending order of the exponents.2x(−x2−x+2)
Factor the quadratic expression: Factor the quadratic expression.Now, we need to factor the quadratic expression -x^\(2 - x + 2").We look for two numbers that multiply to \(-2) (the product of the leading coefficient \(-1) and the constant term \(2)) and add up to \(-1) (the coefficient of the middle term).The numbers \(-2) and \(1) fit this requirement because \(-2 \times 1 = −2) and \(-2 + 1 = −1).
Write factored form: Write the factored form of the quadratic expression.Using the numbers found in Step 4, we can write the factored form of the quadratic expression as (−x+1)(x−2).
Combine GCF with factored expression: Combine the GCF with the factored quadratic expression.Combine the GCF, 2x, with the factored form of the quadratic expression to get the completely factored form of the original polynomial.2x(−x+1)(x−2)
