Q. Factor completely:\newline2y127y6h2+5h4 2 y^{12}-7 y^{6} h^{2}+5 h^{4} \newlineAnswer:
  1. Identify Factor: Identify the common factor in each term.\newlineIn this case, there is no common factor across all three terms.
  2. Pattern or Grouping: Look for patterns or factor by grouping.\newlineSince there are three terms, we can consider if the polynomial is a quadratic in disguise with respect to y6y^6. Let's substitute y6y^6 with zz and rewrite the polynomial.\newlineLet z=y6z = y^6. Then the polynomial becomes 2z27zh+5h42z^2 - 7zh + 5h^4.
  3. Factor Quadratic Polynomial: Factor the quadratic polynomial in zz. We are looking for two numbers that multiply to 2×5h42\times 5h^4 (10h410h^4) and add up to 7h-7h. These numbers are 2h-2h and 5h-5h. 2z27zh+5h42z^2 - 7zh + 5h^4 can be factored as (2z5h)(zh)(2z - 5h)(z - h).
  4. Substitute Back: Substitute y6y^6 back in for zz. Replace zz with y6y^6 in the factored form to get (2y65h)(y6h)(2y^6 - 5h)(y^6 - h).
  5. Check Factored Form: Check the factored form by expanding it to ensure it matches the original polynomial.\newline(2y65h)(y6h)=2y6y6+2y6(h)5hy65h(h)(2y^6 - 5h)(y^6 - h) = 2y^6 \cdot y^6 + 2y^6 \cdot (-h) - 5h \cdot y^6 - 5h \cdot (-h)\newline=2y122y6h5y6h+5h2= 2y^{12} - 2y^6h - 5y^6h + 5h^2\newline=2y127y6h+5h2= 2y^{12} - 7y^6h + 5h^2\newlineThis matches the original polynomial, so the factoring is correct.
