Answer:
[tex]5x - 7 {x}^{2} - {(2x)}^{2} \\ = ( {2}^{2} {x}^{2} ) - 7 {x}^{2} + 5x \\ = 4 {x}^{2} - 7 {x}^{2} + 5x \\ = x(4x - 7x + 5) \\ = x( 5 - 3x) \\ = { \underline{ \underline{ \: \: 5x - 3 {x}^{2} \: \: }}}[/tex]
Hey there!
5x - 7x^2 - (2x)^2
= 5x - 7x^2 - 4x^2
COMBINE the LIKE TERMS
(5x) + (-7x ^2 - 4x^2)
= -7x^2 - 4x^2 + (5x)
= -11x^2 + 5x
Therefore, your answer is: -11x^2 + 5
Good luck on your assignment and enjoy your day!
