Answer 1

\(=-x\left(13x^2-x+11x^2+4x\right)\)

\(=-x\left(24x^2+3x\right)\)

\(=-3x^2\left(8x+1\right)\)

Answer 2

f) - x² (13x - 1) + x (11x² + 4x)

=> - x (13x² - x + 11x² + 4x)

=> - x (24x² + 3x)

=> - 3x (8x + 1)

Answer 3

$=-x\left(13{}^{}-x+11{}^{}+4x\right)$

$=-x\left(24{}^{}+3x\right)$

$=-3{}^{}\left(8x+1\right)$
