Question

Fill in the blanks :-
if p(a) = 2 a^3-6a² -15a + 8
Then P (1) =​

Answer 1

Answer:

-11

Step-by-step explanation:

p(a) = 2a^3 - 6a^2 - 15a + 8

p(1) = 2 1^3 - 6 1^2 - 15 ×1 + 8

p (1) = 2 - 6 - 15 + 8

p(1) = -19 + 8

p(1) = -11

Remember that when you are solving polynomials. You don't have to use BODMAS!

Answer 2

Answer:

$p( a) = {2a}^{3} - 6 {a}^{2} - 15a + 8$

$p(1) = 2(1) ^{3} - 6(1) ^{2} - 15(1) + 8$

$2 - 6 - 15 + 8$

$= - 11$
