Factor Common Terms: Look for common factors in the first two terms and the last two terms separately.First two terms: 18h3+9h2 can be factored by taking out 9h2 as a common factor.9h2(2h+1)Last two terms: 16h+8 can be factored by taking out 8 as a common factor.8(2h+1)
Combine Terms: Now we have:9h2(2h+1)+8(2h+1)Notice that (2h+1) is a common factor in both terms.We can factor (2h+1) out of the expression.(2h+1)(9h2+8)
Final Factored Form: Check for any further factoring possibilities.The terms inside the second set of parentheses, 9h2+8, do not have any common factors and cannot be factored further.So, the factored form of the polynomial is:(2h+1)(9h2+8)
