(x+5)x(5x-1)= tolong jawab ya kaka

Tanda . bisa juga dipakai untuk menyatakan tanda kali (×)

(x + 5)(5x - 1)
= (x . 5x) + (5 . 5x) + (x . (-1)) + (5 . (-1))
= 5x² + 25x - x - 5
= 5x² + 24x - 5

(x + 5)×(5x - 1)
= 5x^2 - 1x + 25x - 5
= 5x^2 + 24x - 5
= (5x + 25) (5x - 1) : 5
= (x + 5) (5x - 1)
x + 5 = 0
x = -5

5x - 1 = 0
5x = 1
x = 1/5
