#### Answer

4(p+2)(3p-1)

#### Work Step by Step

You are given $12p^{2}$+20p-8. Factor it out:
4($3p^{2}$+5p-2) -factor out the common factor of 4-
4($3p^{2}$+6p-p-2) -break out the middle value-
4($3p^{2}$+6p)(-p-2) -group the first two and last two terms-
4(3p($p^{2}$+2)-1(p+2) -Find the GCF of each grouping's-
4(p+2)(3p-1) -factor out the common term-
=4(p+2)(3p-1)
