Question 22 of 25Find the solutions to x² = 27.O A. x = ±9.3O B. x= 139OC. x = ±3-√3OD. x = 192

Answer 1

`C)\:\pm3√(3)`

1) Note that this quadratic equation is an incomplete one since the coefficient b is equal to zero.

2) So, we can solve it using another method rather than the quadratic equation.

`\begin{gathered} x^2=27 \\ x_1=√(27),\:x_2=-√(27) \\ x_1=3√(3),\:x_2=-3√(3) \\ \end{gathered}`

Thus, the answer is C
