Question

Solve the equation : 2x^2 + 1 = 0

Answer 1

Answer:

$x^{2}= -\sqrt{2i} / 2$

Step-by-step explanation: Method: ( by finding square root )

$2x^{2} +1 = 0$

( Subtract 1 from both sides. Anything subtracted from zero gives its negation.)

$2x^{2} = -1$   (Divide both sides by 2.)

$x^{2} = -1/2$  (The equation is now solved.)

$x^{2}= \sqrt{2i} / 2$

$x^{2}= -\sqrt{2i} / 2$
