Matematika x^2-4x-8=0 menggunakan rumus ABC​

x^2-4x-8=0 menggunakan rumus ABC​

Jawaban:

[tex]2 \pm2 \sqrt{3} [/tex]

Penjelasan dengan langkah-langkah:

x² - 4x - 8 = 0

a = 1, b = -4, c = -8

[tex]x1.2 = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac} }{2a} [/tex]

[tex] = \frac{4 \pm \sqrt{( { - 4)}^{2} - 4(1)( - 8)} }{2(1)} [/tex]

[tex] = \frac{4 \pm \sqrt{16 + 32} }{2} [/tex]

[tex] = \frac{4 \pm \sqrt{48} }{2} = \frac{4 \pm4 \sqrt{3} }{2} [/tex]

[tex] = 2 \pm2 \sqrt{3} [/tex]
