x^2 - 14 = -10
x^2 = -10 + 14
x^2 = 4....take the square root of both sides, eliminating the ^2
x = (+-) sqrt 4
x = 2 and x = -2

Answer:

[tex]x=\pm2[/tex]

Step-by-step explanation:

The given equation is

[tex]x^2-14=-10[/tex]

Add 14 to both sides of the equation.

[tex]x^2=-10+14\\\\x^2=4[/tex]

Now, take square root both sides. Whenever, we take square root both sides, we include plus minus sign

[tex]\sqrt{x^2}=\pm\sqrt{4}[/tex]

On simplifying, we get

[tex]x=\pm2[/tex]
