Bantu nmr 5 yaa pakai cara

Answer 1

X² - (x1 + x2)x + x1×x2
x1 = p² + q
x2 = p + q²
x² - ((p²+q) + (p+q²))x + (p²+q)(p+q²)
p² + q + p + q²
p² + q² + p + q
(p + q)² - 2pq + (p + q)
(-(-2)/1)² - 2(-1)/1 + (-(-2)/1)
4 + 2 + 2= 8
(p²+q)(p+q²)
p³ + p²q² + qp + q³
p³ + q³ + (pq)² + pq
(p+q)³ - 3pq(p + q) + (pq)² + pq
(-(-2)/1)³ - 3(-1/1)(-(-(2)/1) + (-1/1)² + (-1/1)
8 + 6 + 1 - 1 = 14
x² - 8x + 14
