Question

p(y)=2y³-6y²-5y+7 for y=2

please answer with all steps it is urgent​

Answer 1

Answer:

Given that,

p (y) = 2y³ - 6y² - 5y + 7

∴ p (2)

= 2 (2)³ - 6 (2)² - 5 (2) + 7

= 2 (8) - 6 (4) - 10 + 7

= 16 - 24 - 10 + 7

= {- 11}−11

Answer 2

Answer:

-11

Step-by-step explanation:

p(2)=2y3 - 6y2 -5y + 7

Substituting 2 as 'y'

p(2) = 2*8 - 6*4 -5*2 +7

      = 16-24 -10+7

      = 23-34

      = -11

Or you can do long division method with y-2
