Jika diketahui a=-5 b=3 c.=-2,maka tentukan nilai dari (a+b)²+2abc&(b-c)²! tolong jwb y kak,dgn caranya #terima kasih

dik : a = - 5
: b = 3
: c = -2


1. ( a+b)^ + 2abc
= ( -5+3 ) ( -5+3 ) + 2(-5)(3)(-2)
= (( -5× -5)+(-5×3)+(3×-5)+(3×3))
+((2×-5)+(2×3)+(2×-2))
= (25+(-15)+(-15)+9) + (-10)+6+(-4)
= ( 4 ) + ( -8)
= -4

2. ( b - c )^
= ( 3 -(-2) ( 3-(-2)
= ( 3+2 ) ( 3+2 )
= 5 × 5
= 25




maaf kalo salah
