Answer:

−202x+−142y

Step-by-step explanation:

step one:distribute

(7x)(2)+(y)(2)+−216x+−144y

14x+2y+−216x+−144y

step two:combine like terms

14x+2y+−216x+−144y

(14x+−216x)+(2y+−144y)

=−202x+−142y

Which special case is represented by x? - 121?

marissa [1.9K]

Answer:

A. the difference of two squares

Step-by-step explanation:

Please use the symbol " ^ " to indicate exponentiation.

Then we have x^2 - 11^2, which is the difference of two squares:

x^2 is a square, the square of x; and 11^2 is a square, the square of 11.

A. the difference of two squares

Note that a "difference of squares" is easily factored:

a² - b² = (a - b)(a + b)

and so your x² - 11² factors as follows: (x - 11)(x + 11)
