What are the possible values of x in - 11x^2 + 2x = 10?

-11x² + 2x = 10

-11x² + 2x - 10 = 10 - 10

-11x² + 2x - 10 = 0

x = - (2) + / - √ ((2) ² - 4 (-11) (-10))

2 (-11)

x = - 2 + / - √ (4 - 440)

-22

x = - 2 + / - √ (-436)

-22

x = - 2 + / - 2i√ (109)

-22

x = - 2 + 2i√ (109) x = - 2 - 2i√ (109)

-22 - 22

x = ¹/₁₁ - ¹/₁₁i√ (109) x = ¹/₁₁ + ¹/₁₁i√ (109)
