Q. Factor completely:\newline16x230x2x3 16 x^{2}-30 x-2 x^{3} \newlineAnswer:
  1. Arrange Polynomial Descending Order: Write down the polynomial and arrange it in descending order of powers of xx. We have the polynomial 16x230x2x316x^2 - 30x - 2x^3. To arrange it in descending order, we rewrite it as 2x3+16x230x-2x^3 + 16x^2 - 30x.
  2. Factor Out Greatest Common Factor: Factor out the greatest common factor (GCF) from the polynomial.\newlineThe GCF of the coefficients 2-2, 1616, and 30-30 is 22. However, since the leading coefficient is negative, we will factor out 2-2 to keep the leading term positive. We also factor out an xx since all terms have at least one xx.\newlineFactoring out 2x-2x, we get 2x(x28x+15)-2x(x^2 - 8x + 15).
  3. Factor Quadratic Expression: Factor the quadratic expression inside the parentheses.\newlineWe need to find two numbers that multiply to give the product ac=15ac = 15 and add to give the middle coefficient b=8b = -8.\newlineThe numbers that satisfy this are 3-3 and 5-5, since (3)×(5)=15(-3) \times (-5) = 15 and (3)+(5)=8(-3) + (-5) = -8.\newlineSo, we can factor the quadratic as (x3)(x5)(x - 3)(x - 5).
  4. Write Fully Factored Form: Write down the fully factored form of the polynomial. Combining the factored out term from Step 22 and the factored quadratic from Step 33, we get the fully factored form of the polynomial: 2x(x3)(x5)-2x(x - 3)(x - 5).
