Question

Tolong jawab ya. pertanyaannya ada di foto.

Answer 1

Fsefgls (a^2 ab b^2
4x^ 2 + 20xy + 25y^2  = (2x + 5y ) ( 2x + 5y)
9x^2 - 42xy + 49y^2    = ( 3x - 7y) ( 3x - 7y )
y^2 + 21y - 72            = ( y + 24 ) ( y - 3 )
6x^2 - 5xy + 6y^2        = (3x - 2y) ( 2x + 3)

Answer 2

4x^ 2 + 20xy + 25y^2 
= (2x + 5y ) ( 2x + 5y)
9x^2 - 42xy + 49y^2  
= ( 3x - 7y) ( 3x - 7y )
y^2 + 21y - 72           
= ( y + 24 ) ( y - 3 )
6x^2 - 5xy + 6y^2       
= (3x - 2y) ( 2x + 3)

semoga membantu :)
