A^2=4
take the square root of both sides
A = ± 2
I HAVE A PROBLEM....
FOR A^2=4 AM I SOLVING FOR A OR ^2?
WILL A BE 2?
4 answers
so this answer is n/a??
No
A = 2 OR A = -2
notice (2)^2 = 4
and (-2)^2 = 4, so they both work
A = 2 OR A = -2
notice (2)^2 = 4
and (-2)^2 = 4, so they both work
SO do I take the square root of both a and 4?
If so square root of a is a and 4 is 2???
If so square root of a is a and 4 is 2???
