tolong bantu jawab kak​

Jawaban:

x² + 7x + 10 = 0

(x + 5) (x + 2) = 0

x = -5 atau x = -2

.....

x² - 7x + 10 = 0

(x - 5) (x - 2) = 0

x = 5 atau x = 2

....

x² + 3x - 10 = 0

(x + 5) (x - 2) = 0

x = -5 atau x = 2

.....

2x² - x - 15 = 0

(2x + 5) (x - 3)

x = -5/2 atau x = 3

....

2x² + 7x + 3 = 0

(2x + 1) (x + 3) = 0

x = -1/2 atau x = -3
