Yang bntuin tuh gmna ya ini

4x - y² + 6y -17 = 0

4x = y² - 6y + 17
x = 1/4 y² - 3/2 y +17/4

x' =0
1/2 y - 3/2 = 0
y - 3 =0
y = 3

x= 1/4 (3)² - 3/2 (3)  + 17/4
x = 9/4 - 9/2  +  17/4
x =  2

(x,y)= (2 , 3)

P(a.b) + T(2,1)=(x,y)
a + 2 = x
a  = x - 2
a =  2-2 = 0

b+ 1 = y
b = y - 1
b = 3 - 1 = 2

a - b = 0 - 2
a - b = - 2

jawaban nya= B -2
semoga bermanfaat
