Question

Remove the brackets and simplify

Answer 1

`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) \: \: }}}`

Answer 2

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!
