Question

18m ao quadrado -2 = 0​

Answer 1

18m² - 2 = 0

utilizando a fórmula de Bhaskara para resolver essa equação, sendo que

a=18,b=0,c=-2.

$\Delta &= b^2-4\cdot a \cdot c\\\\\Delta &=0^2-4\cdot 18\cdot (-2) \\\\\Delta &= 0+144 \\\\\Delta &= 144 \\\\x &= \dfrac{-b\pm\sqrt{\Delta}}{2\cdot a} \\\\x &= \dfrac{-0\pm\sqrt{144}}{2\cdot 18} \\\\x &= \dfrac{0\pm 12}{36} \\\\x_1 &= \dfrac{0 + 12}{36} = \dfrac{12}{36} = \dfrac{1}{3}\\\\x_2 &= \dfrac{0 -12}{36} = \dfrac{-12}{36} = \dfrac{-1}{3}$
