Question

factories 49-x²-16y²+8xy​

Answer 1

(7-X^2-4Y)^2

(7-x+4y)(7-x+4y)

Answer 2

(7 + x - 4y) (7 - x + 4y)

Step-by-step explanation:

49 - x^2 - 16y^2 + 8xy

49 - ( x^2 + 16y^2 - 8xy)

use identity ( a - b)^2

49 - ( x - 4y)^2

7^2 - ( x - 4y)^2

again use identity a^2 - b^2

( 7 + x - 4y) (7 - x + 4y)
