Question 944141: Please can I get help started with this, i cannot move on until the rest of the segment until i get this one done:
Find the real zeros of each polynomial function by factoring. The number in parentheses to the right of each polynomial indicates the number of real zeros of the given polynomial function.
P(x) = x4 − 29x2 + 100 (4)
Let x2 = u, then; x4 − 29x2 + 100 = ???
TIA

x%5E4+-+29x%5E2+%2B+100+=+0

%28x%5E2+-+25%29%28x%5E2+-+4%29+=+0

(x - 5)(x + 5)(x - 2)(x + 2) = 0
