p(x) = 2 + 5x
To find : - p(2) + p(- 2) - p(1) = ?
Now,
p(2) = 2 + 5×2 = 2 + 10 = 12
p(- 2) = 2 + 5×(- 2) = 2 - 10 = - 8
p(1) = 2 + 5×1 = 2 + 5 = 7
So,
p(2) + p(- 2) - p(1)
= 12 - 8 - 7
= - 3
To find : - p(2) + p(- 2) - p(1) = ?
Now,
p(2) = 2 + 5×2 = 2 + 10 = 12
p(- 2) = 2 + 5×(- 2) = 2 - 10 = - 8
p(1) = 2 + 5×1 = 2 + 5 = 7

p(2) + p(- 2) - p(1)
= 12 - 8 - 7
= - 3

ᴘ ( x ) = 2 + 5x
ᴘ ( 2 ) = 2 + 5 × 2 = 2 + 10 = 12
ᴘ ( - 2 ) = 2 + 5 × ( - 2 ) = 2 - 10 = - 8
ᴘ ( 1 ) = 2 + 5 × 1 = 2 + 5 = 7
_________________________
sᴏ ɴᴏᴡ ,
ᴘ ( 2 ) + ᴘ ( - 2 ) - ᴘ ( 1 )
= 12 + ( - 8 ) - 1
= 12 - 8 - 1
= 3
