Question

Jika (y - 5)² = y² + py + q, maka nilai p +q = ....

Answer 1

(y - 5) ² = y² + py + q
y² - 10y + 25 = y² + py + q
p = -10
q = 25

p + q = -10 + 25 = 15

semoga membantu ya :)

Answer 2

(y - 5)² = y² + py + q
y² + 2 ( y) (- 5) + 25 = y² + py + q
y² - 10y + 25 = y² + py + q

jadi
p + q = ....
-10 + 25 = 15
