(x+4)(x+2)=(x+3)(x+5)
`Aljabar
» (x + 4)(x + 2) = (x + 3)(x + 5)
» x(x + 2) + 4(x + 2) = x(x + 5) + 3(x + 5)
» x² + 2x + 4x + 8 = x² + 5x + 3x + 15
» x² + 6x + 8 = x² + 8x + 15
» x² – x² + 6x – 8x = 15 – 8
» (x² – x²) + 6x – 8x = 15 – 8
» 6x – 8x = 15 – 8
» -2x = 7
» x = -7/2
Jawaban:
x = -7/2
Penjelasan dengan langkah-langkah:
x² + 2x + 4x + 8 = x² + 5x + 3x + 15
= 2x + 4x + 8 = 5x + 3x + 15
= 6x + 8 = 8x + 15
= 6x-8x = 15 – 8
= -2x = 7
x = -7 / 2
