Buat cara penyelesaian nya y
Jawaban:
A
(5x – 8)² = (5x – 8) (5x – 8)
(5x – 8)² = (25x² – 40x – 40x +64
(5x – 8)² = 25x² – 80x +64
B
(2x + 3)³ = (2x + 3) (2x + 3) (2x + 3)
(2x + 3)³ = (8x³ + 18x + 12x +27
(2x + 3)³ = 8x³+ 30x +27
(5x – 8)²
= (5x – 8) (5x – 8)
= 25x² – 40x – 40x + 64
= 25x² – 80x + 64
(2x+3)²
2x^2 + 2 + 2x × 3 + 3^2
4x^2 + 12x + 9
