Question

resolver por formula general


3x elevado al cuadrado = -24x-36


por fissss ayudenme........

Answer 1

3X² = -24X - 36

3X² + 24X + 36 = 0

Donde: a = 3; b = 24; c = 36

$X=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

$X=\frac{-24\pm \sqrt{24^2-4(3)(36)}}{2(3)}$

$X=\frac{-24\pm \sqrt{576-432}}{6}$

$X=\frac{-24\pm \sqrt{144}}{6}$

$X=\frac{-24\pm \ 12}{6}$

X1 = [-24 + 12]/6 = -12/6 = -2

X1 = -2

X2 = [-24 - 12]/6 = -36/6 = -6

X2 = -6
