Question

the quadratic
Determind the nature of roots
ean x²-4x+4-0
​

Answer 1

Explanation:

$x { }^{2} - 4x + 4 = 0 \\ comparing \: equation \:with \: \\ ax ^{2} + bx + c = 0 \\ a = 1 \: b = - 4 \: c = 4 \\ b { }^{2} - 4ac = ( - 4) {}^{2} - 4 \times 1 \times 4 \\ = 16 - 4 \\ = 12 \\ here \: b {}^{2} - 4ac > 0 \\ the \: roots \: of \: the \: equation \: are \: \\ real \: and \: unequal$
