Jawaban:
x = 3 dan x = -8
Penjelasan dengan langkah-langkah:
Rumus :
Ax² + Bx + C = 0
x2 + 5x – 24
A = 1 B = 5 C = -24
=> x² + 5x -24 = 0 .... × .... = A × C = 1 ×(-24) = -24 = ( x+8 ) ( x - 3) = 0 ==> 8 × (-3) = -24
x + 8 = 0 atau x - 3 = 0
x = -8 atau x = 3 .... + .... = B = 5
==> 8 + (-3) = 5
jadi nilai x nya adalah
3 dan (-8)
semoga membantu
