2 answers:
Answer:
x^4 + 2x^2 + 1
Step-by-step explanation:
Using Pascal's Triangle, we end up with the following set of coefficients in a triangular form:
1
1 2 1
The coefficients 1, 2 and 1 are used as follows:
1(x^2)^2 + 2(x^2) + 1(1)^2, or
x^4 + 2x^2 + 1
Therefore the given expression (x^2+1)^2 is equivalent to the expanded form x^4 + 2x^2 + 1 .
Answer:
Step-by-step explanation:
(x^2 +1)(x^2 +1)
x^4 +x^2+x^2 +1
x^4+2x^2 +1 answer
