Question

cuál es la respuesta porfavor
4x²-18x+8=0​

Answer 1

Respuesta:

$4 \times {}^{2} - 18 \times + 8 = 0$

$2(2 \times {}^{2} - 9 \times + 4) = 0$

$2 \times {}^{2} - 9 \times + 4 = 0$

$\times = \frac{ - ( - b + \sqrt{b {}^{2} - 4ac} }{2a}$

$2 \times {}^{2} - 9 \times + 4 = 0$

$a = 2$

$b = - 9$

$c = 4$

$\times = \frac{ - ( - 9 + \sqrt{( - 9) {}^{2} - 4.2.4 } }{2.2}$

$\times = \frac{ 9 + 7 }{4}$

$\times = \frac{9 - 4}{4}$

$\times = 4$

$\times = \frac{1}{2}$
