Question

(x-1) (x+3) = 2x+4

Halo kak Tolong bantu pakai cara nya yaa Terimakasih

Answer 1

x = -√7 atau x = √7

Penjelasan dengan langkah-langkah:

(x-1) (x+3) = 2x+4

x² + 3x - x - 3 = 2x + 4

x² + 2x - 3 = 2x + 4

x² + 2x - 3 - 2x - 4 = 0

x² - 7 = 0

x² = 7

x = ±√7

x = -√7 atau x = √7

Answer 2

Penjelasan dengan langkah-langkah:

(x - 1)(x + 3) = 2x + 4

x(x + 3) - 1(x + 3) = 2x + 4

x² + 3x - 1x - 3 = 2x + 4

x² + 2x - 3 = 2x + 4

x² + 2x - 3 - 2x - 4 = 0

x² + 2x - 2x - 3 - 4 = 0

x² - 7 = 0

x = ±√7

x = -√7 atau x = √7

HP{-√7, √7}
