Question

give me answer for this
I will give u chocolate

Answer 1

Hence a=-23 and b=38

Answer 2

ʜᴇʟʟᴏ ᴍᴀᴛᴇ!

p(x) = 2x³ - 3x² + ax + b

Here, x = 2, 3

p(2) = 2(2)³ - 3(2)² + a(2) + b

0 = 16 - 12 + 2a + b

0 = 4 + 2a + b ________(1)

p(3) = 2(3)³ - 3(3)² + a(3) + b

0 = 54 - 27 + 3a + b

0 = 27 + 3a + b _______(2)

(2) - (1)

0 = 27 + 3a + b

- ( 0 = 4 + 2a + b )

=> 0 = 23 + a

Therefore, a = - 23

Then,

0 = 4 + 2a + b

0 = 4 + 2(-23) + b

0 = 4 - 46 + b

42 = b

Hope it helps
