a = 9
d = 17-9 = 8
sum = n/2 (2a+(n-1)d)
636 = n/2 (18+ (n-1)8)
636 = n/2 (18+8n-8)
636 = n/2 (10+8n)
636 = n (5+4n)
636 = 5n +4n2
or 4n2 + 5n - 636 = 0
4n2 + 53n - 48n - 636 = 0
n (4n-53) - 12 (4n-53) = 0
(4n-53) (n-12) = 0
n= 53/4 as number of terms can't be in decimals. so this can't be our answer
therefore, n = 12 is correct answer

x + y = 18
let x be 18-y
so,
(18-y)² + y² = 290
18²+ y² - 36y + y² = 290
2y² - 36y = -34
2y² - 36y +34 = 0
solving the equation
y² -34y-2y+68 = 0
y(y-34) -2( y-34) = 0
(y-2) (y-34) = 0
so,
y= 2 or 34
case 1,
y =2 and x = 16
case 2
y = 34
x = -16

Let α and β be the zeros of the polynomial 4x²-8kx-9
It is given that α=-β
Then, α+β=0
-b/a = 0
-(coefficient of x)/coefficient of x²=0
8k/4 = 0
2k = 0
k = 0
