Answer:

[tex]7x^2-2x+4[/tex]

Step-by-step explanation:

[tex](5x^2+2x+11)-(7+4x-2x^2)[/tex]

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

[tex]5x^2+2x+11-7-4x+2x^2[/tex]

Combining like terms:

[tex](5x^2+2x^2)+(2x-4x)+(11-7)[/tex]

add/subtract like terms:

[tex]7x^2-2x+4[/tex]
