Question

Kk tolong antuin ya

Answer 1

Y=X²-4X-5
(X+1)(X-5)=0
X=-1/ X=5
Gak tau benar / salah
smg membantu

Answer 2

X² - 4x - 5 = 0
(x + 1)(x - 5) = 0
x = -1 atau x = 5
Luas = integ [-1 s.d 5] (x² - 4x - 5) dx
= (1/3)x³ - 2x² - 5x [-1 s.d 5]
= ((1/3)(125) - 2(25) - 25)) - ((1/3) - 2 + 5))
= (125/3 - 75) - (1/3 + 7)
= -124/3 - 82
= -124/3 - 246/3
= -370/3


L=370/3
tanda - karna arahnya kebawah

semoga membantu :)
