#(2x-1)(6x-7)=12x^2-20x+7#

Explanation:

You can use the FOIL mnemonic to help you enumerate all of the products to add as follows:

#(2x-1)(6x-7)#

#= overbrace((2x)(6x))^"First"+overbrace((2x)(-7))^"Outside"+overbrace((-1)(6x))^"Inside"+overbrace((-1)(-7))^"Last"#

#=12x^2-14x-6x+7#

#=12x^2-20x+7#
