Question

Solve p(x)=x4 + 81x2 in comma seperated list

Answer 1

p(x)=x^4 + 81x^2
p(x)=t^2 + 81t, t = x^2
solve using quadratic rules.

Answer 2

\[P(x)=x ^{4 }+81x ^{2}\]

Answer 3

exactly.

Answer 4

is that what they consider factor p completely...man I should have paid more attention

Answer 5

p(x)=x^4 + 81x^2
p(x)=t^2 + 81t, t = x^2
p(x)=t(t+81)
t=0, t=-81
x^2=0, x^2=-81
x^2=0, no other solutions.

Answer 6

x=0 is the answer to p(x) = 0

Answer 7

did i do this one right then...\[p(x)=x ^{4}+6x ^{2}+9\]

Answer 8

i got \[(x ^{2}+3)(x ^{2}+3)\]
