$6(x^2-2x-5)$
Write the prime factors of each term and identify the common factors. Multiply the common factors to find the greatest common factor. $6x^2=\underline2\times\underline3\times x\times x$ $12x=2\times\underline2\times\underline3\times x$ $30=\underline2\times\underline3\times5$ GCF=$2\times3=6$ $6x^2-12x-30=6(x^2-2x-5)$
