tolong dibantu kak soal mtk,,

y = x^2 - 6x + 5 => x = a
y = a^2 - 6a + 5 => (a, a^2 - 6a + 5)

y = x^2 - 6x + 5
y' = 2x - 6
m = y' = 2a - 6

Persamaan garis singgung
y - y1 = m(x - x1)
y - (a^2 - 6a + 5) = (2a - 6) (x - a)
y = (2a - 6)x - a(2a - 6) + (a^2 - 6a + 5)
y = (2a - 6)x - 2a^2 + 6a + a^2 - 6a + 5
y = (2a - 6)x - a^2 + 5

^ = pangkat
