Solve the equation using square roots. x2 – 14 = –10

A. no real number solutions

B. 2

C. + - 2

D. + - 4

Respuesta :

Answer:

C. + - 2

Step-by-step explanation:

first you get rid of -14 by adding 14 to both sides, that leaves you with x2 = 4, then you square root both sides to get the "x" by itself. since you square rooted the problem the answer will always be + or - because you don't know if the variable "x" was truly a + or -.
