Lv 4. x³ + 4x² + 5x + 20 = x²(x + 4) + 5(x + 4) = (x² + 5)(x + 4) Therefore, factors of the given expression are (x² + 5) and (x + 4). First we must note that a common factor does not need to be a single term. They are 2y(x + 3) and 5(x + 3). Quick-Start Guide. Once in the factored form, solve for x by multiplying to get zero. Therefore, 15 plus 5x factors out to 5(3+x). xy + 5x - 4y - 20 = xy - 4y + 5x - 20 = y(x - 4) + 5(x - 4) = A: (y + 5)(x - 4) = P.S. factor x^3-4x^2-5x+20 Answer by Theo(10415) (Show Source): You can put this solution on YOUR website! Hint: Use the equation calculator for equations (containing = signs). The factoring method works because the x-intercepts on the graph of a quadratic function are equidistant from the axis of symmetry, the vertical line passing through the vertex. Not every quadratic expression is factorable, but if they tell you to factor, you can assume it is factorable. x^2(x+5) - 4(x+5) = 0 . 5x+xy-20-4y.
