Question

despeja s=(m(m+1))/3 para m

Answer 1

Hola (｡•̀ᴗ-)✧

Respuesta:

$\boxed{\huge{m = \frac{-1\pm\sqrt{12s+1}}{2}}}$

Explicación paso a paso:

s=(m(m+1))/3

3s = m(m+1)

3s = m²+m

m²+m - 3s = 0

m = (-b±√(b²-4ac))/2a

m = (-1±√(1²-4(1)(-3s)))/2(1)

m = (-1±√(1+12s))/2

$\boxed{\huge{m = \frac{-1\pm\sqrt{1+12s}}{2}}}$
