================================
[tex]1. \: \: 25x² - 4[/tex]
[tex]\rm\underline{Solution:}[/tex]
- [tex]25x² + 10x - 10x⁴[/tex]
- [tex]5x(5x + 2) - 2(5x + 2)[/tex]
Therefore, the answer is
- [tex](5x - 2) (5x + 2)[/tex]
================================
[tex]2. \: \: x2 + 3x - 18[/tex]
[tex]\rm\underline{Solution:}[/tex]
- [tex]x² + 6x - 3x - 18[/tex]
- [tex]x(x + 6) - 3(x + 6)[/tex]
Therefore, the answer is
- [tex](x - 3) (x + 6)[/tex]
================================
[tex]3. \: \: 4x + 2y - (x²)[/tex]
[tex]\rm\underline{Solution:}[/tex]
- [tex]4x + 2y - 1 x²[/tex]
Therefore, the answer is
- [tex]-x² + 4x + 2y[/tex]
================================
