Exploring a Matrix

This activity shows you how to perform several matrix operations.

9. Take the square root of both sides of the

equation with the constraint that

a>0

and

b>0

and

x>0

10. Solve for

by subtracting

from both

sides and then dividing by

Note:

This is only one of the two general

quadratic solutions due to the constraint
in step 9.
