Question

Tolong bantu saya secepatnya di kumpul besok​

Answer 1

Jawaban:

A. 6

B. -16

C. -128

Penjelasan:

[tex]x {}^{2} + 6x - 16 = 0 \\ (x - 8)(x - 2) \\ x1 = 8 \\ x2 = - 2[/tex]

Maka :

[tex]x1 + x2 = 8 + ( - 2) = 6 \\ x1 \times x2 = 8 \times ( - 2) = - 16 \\ x 1 {}^{2} + x2 = 8 {}^{2} \times ( - 2) = - 128[/tex]

Semoga Membantuu:)
