[tex] \large{ \tt{✤ \: FIRST ,\: MEMORISE \: THESE}} : [/tex]
- [tex](a + b)^{2} = {a}^{2} + 2ab + {b}^{2} [/tex]
- [tex] (a - b) ^{2} = {a}^{2} - 2ab + {b}^{2} [/tex]
- [tex] {a}^{2} - {b}^{2} = (a + b)(a - b)[/tex]
- [tex] {a}^{2} + {b}^{2} = {(a + b)}^{2} - 2ab \: [/tex] or [tex] {(a - b)}^{2} + 2ab[/tex]
[tex] \large{ \tt{❁ \: LET'S \: START}} : [/tex]
[tex] \large{ \tt{⋆ \: (x - 5) ^{2} }}[/tex]
- Use the formula of ( a - b ) ². Assume ' x ' as ' a ' & ' 5 ' as ' y ' :
[tex] \large{ \tt{↦ {x}^{2} - 2 \times x \times 5 + {5}^{2} }}[/tex]
[tex] \boxed{ \large{ \tt{↦ \: {x}^{2} - 10x + 25 }}}[/tex]
- Hence , the required answer is x² - 10x + 25
And we're done! ♡
