soal

4x²-2 = 0

jawab

menggunakan akar :

4x²-2 = 0

2x²–1 =0

2x²= 1

x² = 1/2

x = ±√2/2

X1 = –√2/2

x2 = √2/2

menggunakan persamaan kuadrat :

4x²-2 = 0

4x²-2 = 02x²-1 =0

x = -b±√b²–4ac/2ac

x = –0√0²–4 × 2 × (–1)/2×2

x = ±√0+8/4

x = ±√8/4

x = ±2√2/4

x = 2√2/4

x = –2√2/4

kita sederhana kan, jadi

x1 = –√2/2

x2 = √2/2
