Hasil dari (5x – 4)(5x + 4)
=============
maaf pelit poin krna lgi happy

Penjelasan dengan langkah-langkah:

= (5x – 4)(5x + 4)

= (5x·5x)(5x·4)(-4·5x)(-4·4)

= 25x² + 20x – 20x – 16

= 25x² 16

Jawaban:

 sf(5x - 4)(5x + 4)

 sf(5x times 5x)(5x times 4)( - 4times 5x)( - 4 times 4)

 sf {25x}^{2} + 20x + (- 20x) + ( - 16)

 sf = 25x {}^{2} + ( - 16)
