sederhanakan bentuk aljabar berikut ini 4p(3p + 2q - 7 ) - 3p(5p-4q+2)

4p ( 3p+2q-7 ) - 3p ( 5p-4q+2 )
= ( [tex] 12p^{2} [/tex]+8pq-28p ) - ( [tex] 15p^{2} [/tex]-12pq+6p )
= [tex] 12p^{2} [/tex]-[tex] 15p^{2} [/tex]+8pq-12pq-28p+6p
= [tex] -3p^{2} [/tex]-4pq-22p

(14p^+8pq-28p)-(15p^+12q+6p)
-3p^+20pq-22p
