Tentukan akar persamaan kuadrat berikut dengan rumus abc!
2x²+6x=0

[tex]2x {}^{2} + 6x = 0[/tex]

a = 2

b = 6

c = 0

[tex]x = \frac{ - b \: ± \sqrt{ {b}^{2} } - 4ac }{2a} [/tex]

[tex]x = \frac{ - 6 \: ± \sqrt{ {6}^{2} - 4(2)(0)} }{2(2)} [/tex]

[tex]x = \frac{ - 6 \: ±\sqrt{36 - 0} }{4} [/tex]

[tex]x = \frac{ - 6 \: ± \sqrt{36} }{4} [/tex]

[tex]x = \frac{ - 6 \: ± \: 6 }{4} [/tex]

--------------------------------

[tex] {x}^{1} = \frac{ - 6 + 6}{4} [/tex]

[tex] {x}^{1} = \frac{0}{4} [/tex]

[tex] {x}^{1} = 0[/tex]

--------------------------------

[tex] {x}^{2} = \frac{ - 6 - 6}{4} [/tex]

[tex] {x}^{2} = \frac{ - 12}{4} [/tex]

[tex] {x}^{2} = - 3[/tex]
