Find GCF: First, we look for a greatest common factor (GCF) that can be factored out from all the terms of the polynomial 6x2+28x+16. The GCF of 6, 28, and 16 is 2.
Factor out GCF: We factor out the GCF from each term of the polynomial: 2(3x2+14x+8)
Factor quadratic expression: Next, we need to factor the quadratic expression inside the parentheses. We look for two numbers that multiply to 3×8 (24) and add up to 14. The numbers that satisfy these conditions are 12 and 2 because 12×2=24 and 12+2=14.
Write as binomials: We can now write the quadratic expression as a product of two binomials: 2(3x2+12x+2x+8)
Group terms to factor: We group the terms to factor by grouping: 2((3x2+12x)+(2x+8))
Factor out common factors: Factor out the common factors from each group: 2(3x(x+4)+2(x+4))
Final factorization: We notice that (x+4) is a common factor in both groups, so we factor it out: 2(3x+2)(x+4)
