Question

find p(1)+p(-1)+p(10) if p(x)= x²-3x+2


​

Answer 1

Answer:

Given that ;

p( x ) = x² - 3x + 2

Values :

x = 1 , -1 , 10

Hence ;

p ( 1 ) = ( 1 )² - 3 ( 1 ) + 2

p ( 1 ) = 1 - 3 + 2

p ( 1 ) = - 2 + 2

p ( 1 ) = 0

Now ,

p ( - 1 ) = ( - 1 )² - 3 ( -1 ) + 2

p ( -1 ) = 1 + 3 + 2

p ( - 1 ) = 6

Then ,

p ( 10 ) = ( 10 )² - 3 ( 10 ) + 2

p ( 10 ) = 100 - 30 + 2

p ( 10 ) = 72

Asked That ;

p( 1 ) + p( -1 ) + p( 10 )

0 + 6 + 72

78
