Question

9 − (x 2 − 4x + 4) factorize

Answer 1

$\large{ \boxed{ \boxed { \sf{answer : }}}}$

$\sf{9 - (x { }^{2} - 4x + 4) } \\ \sf{9 - x {}^{2} + 4x - 4 } \\ \sf{ - x {}^{2} + 4x + 5 } \\ \sf{x {}^{2} - 4x - 5 } \\ \sf{x {}^{2} - 5x + x - 5 } \\ \sf{x(x - 5) + 1(x - 5)} \\ \underline{\underline{ \sf{(x - 5)(x + 1)}}}$
