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

x = ±2

Step-by-step explanation:

x^2 – 14 = –10

Add 14 to each side

x^2 – 14+14 = –10+14

x^2 = 4

Take the square root of each side

sqrt(x^2) = ±sqrt(4)

x = ±2

D) Amplitude;2 ; midline: y= 2

Step-by-step explanation:

The total height of the curve = 4

Amplitude = 4/2 = 2

The middle line is y = 2

Therefore, answer is D) Amplitude;2 ; midline: y= 2

Hope this will helpful.

Thank you.
