Answer 1

${\large{\underbrace{\textsf{\textbf{\color{red}{➵}{\color{green}{\:\:ANSWEɾ\: :-}}}}}}}$

Let z = x² - 2x

Then $\sf F = z² - 2 z - 3$

$\sf = (z - 3) (z + 1)$

$\sf = ( x² - 2x - 3) (x² - 2x + 1)$

$\sf = (x -3 ) (x + 1) (x - 1)²$

Answer 2

$x^2-(2x)^2-2x^2-2x-3 \\ in \: this \: factorize \: i \: will \: simplify \: it \: so \: that \: it \: can \: be \: easir$

$let \: x {}^{2} - 2x = y$

$y {}^{2} - 2y - 3$

$(y - 3)(y + 1)$
