Question

write down the products for each of the following 1. (x+4) (x+2) 2. (4a-5) (5a+6) 3. (xy+6) (xy-5)​

Answer 1

1) x²+6x+8

2)20a²-x-30

3)x²y²+xy-30

Answer 2

Answer:

see the following explanation

Step-by-step explanation:

i) (x+4)(x+2)=x²+6x+8

ii) (4a-5)(5a+6)=20a²-25a+26a-30

=20a²+a-30

iii) (xy+6)(xy-5)=x²y²-5xy+6xy-30

x²y²+xy-30
