(y³ + 3) (-4y² + 5y + 6)
-4y⁵+ 5y⁴ + 6y³ - 12y² + 15y + 18
(2x + 3)³
saya pakai segitiga pascal ya!
(1) (2x)³ + (3) (2x)² (3) + (3) (2x) (3)² + (1) (3)³
12x³ + 36x² + 52x + 27
5 - 3
(x² + 5x - 6) (x - 1)
5 - 3
(x - 1) (x + 6) (x - 1)
5 - 3(x + 6)
(x- 1) (x + 6) (x - 1) (x + 6)
5 - 3(x + 6)
(x - 1) (x + 6)
2
(x - 1)
jadikan jawaban ini sebagai jawaban yang terbaik !!!!!!!!
⇒ (y³ + 3) (-4y² + 5y + 6)
⇒ -4y⁵+ 5y⁴ + 6y³ - 12y² + 15y + 18
2. (2x + 3)³ = (2x)³ + 3 (2x) ² (3) + 3 (2x)(3) ² +(3)³
= 8x³ + 36x² + 108x² + 27
= 8x² + 144x² + 27
rumus : (a+b)³ = a³ + 3a²b + 3ab² +b³
3. 5 - 3 = 5 - 3
(x²+5x-6) (x-1) (x+2) (x+3) (x-1)
= 5 - 3(x + 6)
(x- 1) (x + 6) (x - 1) (x + 6)
= 5 - 3(x + 6)
(x - 1) (x + 6)
= 2
(x - 1)
