Answer 1

Verified answer

Respuesta:

[tex]4 \times {}^{2} - 18 \times + 8 = 0[/tex]

[tex]2(2 \times {}^{2} - 9 \times + 4) = 0[/tex]

[tex]2 \times {}^{2} - 9 \times + 4 = 0[/tex]

[tex] \times = \frac{ - ( - b + \sqrt{b {}^{2} - 4ac} }{2a} [/tex]

[tex]2 \times {}^{2} - 9 \times + 4 = 0 [/tex]

[tex]a = 2[/tex]

[tex]b = - 9[/tex]

[tex]c = 4[/tex]

[tex] \times = \frac{ - ( - 9 + \sqrt{( - 9) {}^{2} - 4.2.4 } }{2.2} [/tex]

[tex] \times = \frac{ 9 + 7 }{4} [/tex]

[tex] \times = \frac{9 - 4}{4} [/tex]

[tex] \times = 4[/tex]

[tex] \times = \frac{1}{2} [/tex]
