Question

2x² + 15x = 18. ayuda
​

Answer 1

Respuesta:

$2 \times {}^{2} + 15 = 18$

$2 \times {}^{2} + 15 \times - 18 = 0$

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

$2 \times {}^{2} + 15 \times - 18 = 0$

$a = 2$

$b = 15$

$c = - 18$

$\times = \frac{ - 15 \frac{ + }{} }{} \frac{ \sqrt{15 {}^{2} - 4.2( - 18)} }{2.2}$

$\times = \frac{ - 15 + 3 \sqrt{41} }{4}$

$\times = \frac{ - 15 - 3 \sqrt{41} }{4}$

$\times = \frac{ - 15 \frac{ + }{} }{} \frac{3 \sqrt{41} }{4}$
