The equivalent expression to [tex](4-7)(2x-1)[/tex] is [tex]-6x+3[/tex]
First, you multiply the binomials using the multiplying binomial that you are used to. I like to use the box method.
Multiply 4 by 2x and -1 and multiply -7 by 2x and -1
[tex]8x-14x-4+7[/tex]
Then, add like terms.
[tex]-6x+3[/tex]
