Sagot :

Answer:

( a+b) (a-b)

x^2 - 50

Step-by-step explanation:

The formula for difference of squares is

a^2 - b^2 = ( a+b) (a-b)

121x^2 -144 = (11x)^2 - 12^2 so this is the difference of squares

x^2 - 16y^2 = (x)^2 - (4y)^2  so this is the difference of squares

9x^2 -64 = (3x)^2-8^2  so this is the difference of squares

x^2 - 50 = (x)^2 - 2*(5)^2  this is not the difference of squares
