Please help :( I'm really bad at math and bukas na monday yung deadline namin. :(

Test 3. Problem Analysis
1. Is 9x³y6⁶- 1 a difference of two squares? Explain.
2. Is 27x³y⁶ + z⁹ a sum of two cubes? Explain.
3. If the given polynomial is a perfect square trinomial, can we also use the technique in factoring general trinomials (x² + bx + c and ax² + bx + c) in finding it's factors? Explain.

TEST 4. ERROR ANALYSIS

4. Which of the following solutions is correct? Explain.
Solution 1:
[tex]\frac{m^{2} - 25 }{2m - 10} [tex]\frac{mx^{2} - 25 }{2m - 10} ÷ \frac{m+5}{14m} = \frac{mx^{2} = 25}{2m - 10} x \frac{14m}{m + 5} = \frac{(m+5)(m+5)}{2(m+5)} x\frac{14m}{m+5} = \frac{14m}{2} = 5m

Solution 2
[/tex] \frac{m + 5}{14m} =\frac{m^{2} - 25 }{2m - 10} x\frac{14m}{m + 5} = \frac{(m-5) (m+5)}{2(m-5)} x \frac{14m}{m + 5} = \frac{14m}{2} = 7m[/tex]
