Factoring 8y3+16y224y8y^3 + 16y^2 - 24y

To factor the polynomial 8y3+16y224y8y^3 + 16y^2 - 24y completely, start by identifying the greatest common factor (GCF). The GCF of the three terms is 8y8y. Factoring out 8y8y yields 8y(y2+2y3)8y(y^2 + 2y - 3). The remaining expression in the parentheses is a trinomial with a leading coefficient of 11. Find two numbers that multiply to 3-3 and add to 22, which are 33 and 1-1. This gives the binomial factors (y+3)(y + 3) and (y1)(y - 1). The final completely factored form is 8y(y+3)(y1)8y(y + 3)(y - 1). Multiply the factors to check the result.
