Identify Factor: Identify the common factor in each term.In this case, there is no common factor across all three terms.
Pattern or Grouping: Look for patterns or factor by grouping.Since there are three terms, we can consider if the polynomial is a quadratic in disguise with respect to y6. Let's substitute y6 with z and rewrite the polynomial.Let z=y6. Then the polynomial becomes 2z2−7zh+5h4.
Factor Quadratic Polynomial: Factor the quadratic polynomial in z. We are looking for two numbers that multiply to 2×5h4 (10h4) and add up to −7h. These numbers are −2h and −5h. 2z2−7zh+5h4 can be factored as (2z−5h)(z−h).
Substitute Back: Substitute y6 back in for z. Replace z with y6 in the factored form to get (2y6−5h)(y6−h).
Check Factored Form: Check the factored form by expanding it to ensure it matches the original polynomial.(2y6−5h)(y6−h)=2y6⋅y6+2y6⋅(−h)−5h⋅y6−5h⋅(−h)=2y12−2y6h−5y6h+5h2=2y12−7y6h+5h2This matches the original polynomial, so the factoring is correct.
