Question

If p(m)=m³+2m²-m+10 then p(a)+p(-a)=?

Answer 1

$\textbf{Answer :}$

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

= $\bold{4a^{2} + 20}$

Answer 2

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

= \bold{4a^{2} + 20}4a
