Question

Which of the following is the cubic polynomial?

a) x + 3x² - 4x + 3
b) 3 x ² + 4
c) 8 (2²+2+1)
d) a² + 4x +7​

Answer 1

Answer:

• c is the cubic polynomial as we can right 8 as 2³
• we can write 8 as 2³ so the part c can be written as 2³(2²+2+1)
• then we can elaborate that the part c is a cubic polynomial

Answer 2
