x²-2x+5
putting the value of x= -1
so,(-1)²-2×-1+5
1+2+5=8
putting the value x=5
5²-2×5+5
25-10+5=20

polynomial is given =
x² - 2x +5
p ( x ) = -1
therefore ,
p ( -1 ) = x² - 2x + 5
=> ( -1) ² - (-1 × 2 ) + 5
=> 1 + 2 + 5
=> 8
when x = 5
p ( x) = x² - 2x + 5
p ( 5 ) = ( 5 ² ) -2 × 5 + 5
=> 25 -10 + 5
=> 20
hence , your answer is
★ 8 , 20 ★
hope it helps you dear!!
