Jumlah p dan q adalah 12. nilai minimum dari 2p²+q²=…
Jawaban Terkonfirmasi
P+q = 12
p = 12-q
2p²+q² = 2(12-q)²+q²
= 2 (144-24q+q²)+q²
= 288-48q+2q²+q²
= 3q²-48q+288
a=3, b = -48, c = 288
minimum saat q = -b/2a
= -(-48)/2.(3)
= 8
p+q = 12
p+8 = 12
p = 4
nilai minimum : 2p²+q² = 2(4)²+8²
= 32+64
= 96
