Answer:
13i, -13i
Step-by-step explanation:
x^2=-169
169=(13)^2
x^2=-(13)^2
the square root of -1 is i ( imaginary number )
(-13)^2=(13)^2 so x is 13i and -13i
Answer:
13i
Step-by-step explanation:
So I would solve for x
This is zero term factoring
This is a square root factor and 169's square root is 13.
However we need to factor -169
This is where imaginary numbers come in. i= Square root of -1
13i would be the answer
