PLISSSSSSSSSSSSSSSSSSSSSSSSSS BANTUANYA BSOK DIKUMPUL
PENGURANGAN
1.(a²-ab-b²) dari (b²+ab-3a²) adalahhhh

2..-3(p²-5p+2)dari 5(2p²+p+11)adalahhhh

plisssss dibantu

Answer 1

(b²+ab-3a²) - (a²-ab-b²) = b²+ab-3a²-a²+ab+b²
                                 = 2b²+2ab-4a²
5(2p²+p+11)-(-3(p²-5p+2)) = 10p²+5p+55+3p²-15p+6
                                     = 13p²-10p+61

Answer 2

1.b²+ab-3a² - (a²-ab-b²)= b²+ab-3a²-a²+ab+b² = -3a²-a²+ab+ab+b²+b² =-4a²+2ab+2b²

2.5(2p²+p+11)-(-3(p²-5p+2))=10p²+5p+55 - (-3p²+15p-6) = 10p²+5p+55+3p²-15p+6 = 10p²+3p²+5p-15p+55+6= 13p²-10p +61
