tolong bantu ya kawan,mkasih.

jawabannya x²+6x+8...semoga membantu

2x² + 3x + 1 = 0
a = 2
b = 3
c = 1

a + B = -b/a = -3/2
a × B = c/a = 1/2

Persamaan kuadrat baru
x² - (x1 + x²) x + x1 . x2 = 0
x² - (2/a + 2/B) x + 2/a × 2/B = 0
x² - [2(a + B)/aB] x + 4/aB = 0
x² - [2(-3/2)/(1/2)] x + 4/(1/2) = 0
x² + 3 × 2x + 4 × 2 = 0
x² + 6x + 8 = 0
