Question

Factorise -
t²-20t -125​

Answer 1

Question :-

• Factorise :- ${t}^{2}\:-20t\:-125$

Solution :-

${t}^{2} - \: 20t \: - \: 125$

$\implies \: {t}^{2} - 25t \: + 5t \: - 125$

$\implies \: t(t \: - 25) \: + \: 5(t - 25)$

$\implies \: (t \: + 5)(t \: - 25)$

Answer :-

The answer is

$(t \: + \: 5)(t \: - \: 25)$
