2). (x - 4) (x + 2)

3. (x + 2) (x + 5)

4. (x - 3) (x - 4)​

Answer 1

1. = x(x+5 ) 3(x+5)
=x^2 +5x +3x + 15
=x^2 +8x +15
2.

Answer 2

Answer:

1). ( x + 3 ) ( x + 5 )

= x^ + 3x + 3x + 15

= x^ + 6x + 15

2). ( x - 4 ) ( x + 2 )

=x^ + 2x - 4x - 8

= x^ - 2x - 8

3). ( x + 2 ) ( x + 5 )

=x^ + 5x + 2x + 10

= x^ + 7x + 10

4). ( x - 3 ) ( x - 4 )

= x^ - 4x - 3x + 12

=x^ - 7x + 12
