tolong dibantu ya yang bisa dengan caaranya

=4/2+1[tex] x^{2+1} [/tex] - 8/1+1[tex] x^{1+1} [/tex] - 3x
=4/3[tex] x^{3} [/tex] - 8/2[tex] x^{2} [/tex] - 3x
=4/3[tex] x^{3} [/tex] - 4[tex] x^{2} [/tex] - 3x
=(4/3(3)³ - 4(3)² - 3(3)) - (4/3(1)³ - 4(1)² - 3(1))
=(4/3(27) - 4(9) - 9) - (4/3 - 4 - 3)
=(36 - 36 - 9) - ( 4/3 - 12/3 - 9/3)
=( -27/3 ) - ( -17/3)
= -27/3 + 17/3
= -10/3 .A
