Question

X2=16x-63formula general​

Answer 1

Fórmula General:

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

Ecuación:

$x^{2} = 16x - 63\\x^{2} -16x+63=0$

a = 1

b = -16

c = +63

$\frac{-(-16) +/- \sqrt{(-16)^{2} - 4(1)(63)} }{2(1)}$

$\frac{16+/-\sqrt{256-252} }{2}$

$\frac{16+/-\sqrt{4} }{2}$

$\frac{16+/-2}{2}$

$x_{1} =\frac{18}{2}=9\\x_{2}=\frac{14}{2} =7$
