plis jawab secepatnya,PKE CARA NOMOR YG DILINGKARI.....

Nomor 73
[tex]64{p}^{2} - 1 = (8p - 1)(8p + 1)[/tex]
Nomor 74
[tex]36 {p}^{2} - 81 {q}^{2} = (6p - 9q)(6p + 9q)[/tex]
Nomor 77
[tex] \frac{ {x}^{2} + 3x}{ {x}^{2} - 9} = \frac{x(x + 3)}{(x + 3)(x - 3)} = \frac{x}{x - 3} [/tex]
Nomor 78
[tex] \frac{ {x}^{2} - 25 }{ {x}^{2} + x - 20} = \frac{(x - 5)(x + 5)}{(x + 5)(x - 4)} = \frac{x - 5}{x - 4} [/tex]
Nomor 79
[tex] \frac{ {x}^{2} + 3x + 2 }{ {x}^{2} - 4 } = \frac{(x + 2)(x + 1)}{(x - 2)(x + 2)} = \frac{x + 1}{x - 2} [/tex]
Nomor 80
[tex] \frac{4 {x}^{2} - 9}{2 {x}^{2} - x - 3 } = \frac{(2x + 3)(2x - 3)}{(2x - 3)(x + 1)} = \frac{2x + 3}{x + 1} [/tex]

79. x² + 3x+ 2
—————
x² - 4
= (x+1)(x+2)
—————— (yang sama dicoret)
(x+2)(x-2)
= (X-1)
——— (D)
(x-2)


coretan:
* x²+3x+2
p+q=3| P:1
p×q=2| Q:2
(X+P)(X+Q)
(x+1)(x-2)
*x² - 4
(x+2)(x-2)
