Question

Tolong ya yang bisa jawab pakai cara please!!!!

Answer 1

1a) a2 + 2ab + b2
62 + 2 (6) (-1) + (-1)2
36 - 12 + 1 = 25
b) a2b - ab2 + a2b2
(6)2(-1) - 6 (-1)2 + (6)2 (-1)2
-36 - 6 + 36 = -6

Answer 2

Jika a=6. dan b =-1
a. a²+2ab+b²
==> 6²+2(6-1)+(-1)²
= 36+12-2 +1
= 36+10+1
= 47
b. a²b-ab²+a²b²
6²(-1)-6(-1)²+6²(-1)²
= -36-6+36
= -6
c.2a+2a²b²+3ab+b²
2(6)+2(6²)(-1)²+3(6-1)+(-1)³
