SOLUTION: How would you solve this? m4 +13m2 − 48 = 0 would you separate the equation out so it's m2(m2+13)-48=0?

Question 396120: How would you solve this?
m4 +13m2 − 48 = 0
would you separate the equation out so it's
m2(m2+13)-48=0?

Assuming the 4 and 2 are exponents,

Sub x for m^2

(x+16)(x-3) = 0
x = 3, -16
----------
Sub back

m = � sqrt(3)
------------

m = � 4i
================

You might factor that, too.

Same answers, simpler, but if factoring isn't possible, substitution always works.
