Answer 1

$\large\underline{\underline{\sf{\color{lime}{SOLUTION :-}}}}$

1) $\sf{x^2-11x-782}$

$\sf{= x^2+23x-34x-782}$

$\sf{= x(x+23) -34(x+23)}$

$\sf{= (x+23)(x-34)}$

→ x = -23 or 34.

2) $\sf{x^2+27x+162}$

$\sf{= x^2+18x+9x+162}$

$\sf{= x(x+18)+9(x+18)}$

$\sf{= (x+18)(x+9)}$

→ x = 18 or -9.

3) $\sf{x^2-12x-325}$

$\sf{= x^2+13x-25x-325}$

$\sf{= x(x+13)-25(x+13)}$

$\sf{= (x+13)(x-25)}$

→ x = -13 or 25.
