Question

If p(y) =2y^3-6th -5y+ 7 then find p (2)

Answer 1

Answer :-

_____________________

Given ,

p ( y ) = 2y³ - 6y² - 5y + 7

To find ,

p ( 2 ) = ?

Now ,

p ( y ) = 2y³ - 6y² - 5y + 7

p ( 2 ) = 2 × 2³ - 6 × 2² - 5 × 2 + 7

= 2 × 8 - 6 × 4 - 10 + 7

= 16 - 24 - 10 + 7

= - 11 [ ★ Required answer ]

Answer 2

Since,

p(y) = 2y³ - 6y² - 5y + 7

so,

p(2) = 2 (2)³ - 6 (2)² - 5 (2) + 7

=> p(2) = 2 × 8 - 6 × 4 - 10 + 7

=> p(2) = 16 - 24 - 3

=> p(2) = 16 - 27

=> p(2) = -11 {answer}

thus, your answer is -11.

hope you understood!
