Question

The quadratic equations x^2-4x+4=0 has indentical (repeated) roots

Answer 1

$\huge{ \underline{ \boxed{ \mathfrak{ \red{answer}}}}} \\ \\ {x}^{2} - 4x + 4 \\ \\ {x}^{2} - 2x - 2x + 4 \\ \\ x(x - 2) - 2(x - 2) \\ \\ (x - 2)(x - 2)$

Take,

x-2=0 and x-2=0

x=2 and x=2

Hence it has repeated roots.
