Question

Como resolver -7m+2m²+2

Answer 1

con la Formula general:

$a^{2} +b+c=0\\\\Entonces:\\\\\frac{-b+-\sqrt{b^{2}-4(a)(c)}}{2(a)}$

$-7m+2m^{2} +2=\\2m^{2} -7m+2\\\\\frac{7+-\sqrt{49-4(2)(2)}}{4}=\\\\\frac{7+-\sqrt{33}}{4}= \\\\caso1\\\\\frac{7+\sqrt{33}}{4} =3.18\\\\caso2\\\\\frac{7-\sqrt{33}}{4} =0.31$
