Question

(3x+5y) (3x - 5y ))

 

Answer 1

(3x+5y) (3x - 5y )

=9x²-15xy+15xy-25y²

=9x²-25y²(-15xy+15xy)

=9x²-25y²

Answer 2

\(\left(3x+5y\right)\left(3x-5y\right)=9x^2-25y^2\)

Answer 3

(3x+5y) (3x - 5y )

=9x²-15xy+15xy-25y²

=9x²-25y²(-15xy+15xy)

=9x²-25y²

Answer 4

(3x+5y) (3x - 5y )

=9x²-15xy+15xy-25y²

=9x²-25y²(-15xy+15xy)

=9x²-25y²

Answer 5

{3x+5y} {3x-5y}

= 9x² -15xy+15xy-25y² 

= 9x² -25y²{ -15xy+15xy}

= 9x² -25y²

Answer 6

(3x+5y)(3x-5y)
=9x-15xy+15xy-25y²
=9x-25y²

Answer 7

nhầm là 9x² nhé

Answer 8

(3x+5y) (3x - 5y )

=9x²-15xy+15xy-25y²

=9x²-25y²(-15xy+15xy)

=9x²-25y²

Answer 9

(3x+5y) (3x - 5y )

=9x²-15xy+15xy-25y²

=9x²-25y²(-15xy+15xy)

=9x²-25y²

Answer 10

(3x+5y) (3x - 5y )

=9x²-15xy+15xy-25y²

=9x²-25y²(-15xy+15xy)

=9x²-25y²

Answer 11

(3x+5y) (3x - 5y )

=9x²-15xy+15xy-25y²
