mohon dijawab yg nomor 2 ya kakak cantik dan ganteng,makasih sblmnyaa..

x² + 2x - 1 = 0
x1 + x2 = -b/a = -2
x1x2 = c/a = -1

akar2 PK baru :
(x1² + x2²) + (1/x1² + 1/x2²) = p
p = ((x1 + x2)² - 2x1x2) + ((x1 + x2)² - 2x1x2)/(x1x2)²
p = (4 + 2) + (4 + 2)/1 = 12

(x1² + x2²) (1/x1² + 1/x2²) = q
q = 1 + 1 + (x2²/x1²) + (x1²/x2²)
q = 2 + (x2/x1 + x1/x2)² - 2)
q = (x2² + x1²)²(x1x2)²
q = (4 + 2)² /1
q = 36

PK baru :
x² + (-p)x + q = 0
x² - 12x + 36 = 0

p + q = -12 + 36 = 24
