Answer:
p(x) - q(x) = 4x²
Explanation:
p(x) - q(x)
= + 2x² + 1 - ( - 2x² + 1) ← distribute parenthesis by - 1
= + 2x² + 1 - + 2x² - 1 ← collect like terms
= 4x²
the answer is 4x2
p(X)-q(X) = x4 + 2x2 + 1 - ( x4 - 2x2 + 1 )
p(X)-q(X) = x4 + 2x2 + 1 - x4 + 2x2 - 1 )
p(X)-q(X) = 2x2 + 2x2
p(X)-q(X) = 4x2
