Question

can someone PLEASE HELP!!
find all real zeros and determine multiplicity of each: f(x)=x^4-52x^2+576

Answer 1

Let f(x) = 0 = x^4-52x^2+576
Then factor: by factoring: (x^2- ?)(x^2- ?) - can you find these numbers?

Answer 2

Find 2 factors of 576 when you add them you get -52 and when you multiply them of course you get 576.
NOTE: The sign on the third term is positive so the sign on the 2 number in the factor will have the same sign as that on the second term.
