Step-by-step explanation:

Answer 2

༒ Required Solution -

$( {5x}^{2} + 2x + 11) - (7 + 4x - {2x}^{2} )$

Breaking the parentheses using the law of signs for addition / subtraction:

$5 {x}^{2} + 2x + 11 - 7 - 4x + 2 {x}^{2}$

Combining like terms:

$(5 {x}^{2} + 2 {x}^{2} ) + (2x - 4x) + (11 - 7)$

add/subtract like terms:

$7 {x}^{2} - 2x + 4$
