Question

Solve for h.
144 = h²

Answer 1

Answer: +12 or -12

Explanation:

h^2=144

taking sqrt root on both sides

h=±12

so answer is +12 or-12

Answer 2

h = 12 OR h = -12

Explanation:

h² means h * h

We can start with a number like "10". 10*10 = 100, so we have to guess a bit higher.

12*12 = 144.

However, it can also be -12 * -12 since the two negative signs will cancel each other out.

So, h can be 12 or -12
