MathTutor 10.

$\frac{1- \frac{36}{x^2} }{4+ \frac{24}{x}}\\= \frac{x^2-36}{x^2}: \frac{4x+24}{x}\\= \frac{x^2-36}{x^2}. \frac{x}{4x+24}\\= \frac{(x-6)(x+6)}{4x(x+6)}\\= \frac{x-6}{4x}$

9.

$\frac{6x^2-4x-2}{x^2-8x+7} \\= \frac{(6x+2)(x-1)}{(x-7)(x-1)}\\= \frac{6x+2}{x-7}$

8.

$\frac{x^2+2x-15}{10x-5}. \frac{4x-2}{4x-12}\\= \frac{(x+5)(x-3)}{5(2x-1)}. \frac{2(2x-1)}{4(x-3)}\\= \frac{(x+5)}{10}$

5. 3x²-13x+10=(3x-10)(x-1)

3. (5x-2y)(6x-3y)=30x²-15xy-12xy+6y²=30x²-27xy+6y²

4. soal tidak jelas.

Semangat!
