Use the properties of real numbers to simplify the expression:
[tex]4(p-7p+3)[/tex]Add like terms inside the parenthesis:
[tex]=4(-6p+3)[/tex]Use the distributive property to eliminate the parenthesis:
[tex]\begin{gathered} =4(-6p)+4(3) \\ =-24p+12 \end{gathered}[/tex]This expression is fully simplified. But it can be factorized by the common factor of 12 (using the distributive property again):
[tex]\begin{gathered} -24p+12=12(-2p)+12(1) \\ =12(-2p+1) \end{gathered}[/tex]
