Use the quadratic formula to solve the equation -3x2-x-3=0

Novosadov [1.4K]

Answer:

$x=\frac{1+\sqrt{35}i}{-6}\,\, and\,\, x=\frac{1-\sqrt{35}i}{-6}\\$

Step-by-step explanation:

the quadratic formula is:

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

a= -2, b = -1 and c =-3

Putting values in the formula

$x=\frac{-(-1)\pm\sqrt{(-1)^2-4(-3)(-3)}}{2(-3)}\\x=\frac{1\pm\sqrt{-35}}{-6}\\x=\frac{1+\sqrt{-35}}{-6}\,\, and\,\, x=\frac{1-\sqrt{-35}}{-6}\\We\,\, know \,\,that \,\,\sqrt{-1} = i \\x=\frac{1+\sqrt{35}i}{-6}\,\, and\,\, x=\frac{1-\sqrt{35}i}{-6}\\$
