Mathematics

$4p^{2}+6p-8$

Step-by-step explanation:

Hello

let's remember

(+)*(+)=(+)

(+)*(-)=(-)

(-)*(-)=(+)

(-)*(+)=(-)

Let

$(1) 2p^{2} +3p-4\\(2)-2p^{2} -3p+4\\\\(1)-(2)\\\\2p^{2} +3p-4 - (-2p^{2} -3p+4)\\\\2p^{2} +3p-4+(-1)(-2p^{2})+(-1)(-3p)+(-1)(+4)\\\\2p^{2} +3p-4 +2p^{2} +3p-4$

Add similar terms

$2p^{2} +3p-4 +2p^{2} +3p-4\\(2p^{2} +2p^{2} )+(3p+3p)+(-4-4)\\4p^{2}+6p-8$

I hope it helps, let me know if I can help you with something else.

Have a nice day.
