Question

3) If p(m) = m^3 + 2m^2- m+ 10 then p(a) + P(- a) = ?
Please give correct answer​

Answer 1

Answer:

Given that,

p (m) = m³ + 2m² - m + 10

So, p (a) = a³ +2a² - a + 10

and p (- a) = (- a)³ + 2(- a)²- (- a) + 10

= - a³ + 2a² + a + 10

Then, p (a) + p (- a)

= a³ +2a² - a + 10 - a³ + 2a² + a + 10

= $4a^{2} + 20$
