Identify Common Factor: Look for a common factor in all terms.The polynomial is 2x2+32x+126. We can see that all terms are even numbers, so we can factor out a 2.2(x2+16x+63)
Factor Quadratic Expression: Factor the quadratic expression inside the parentheses.We need to find two numbers that multiply to 2×63=126 and add up to 16. These numbers are 9 and 7.2(x+9)(x+7)
