Question

find the products :-​

Answer 1

Answer:

1. X²+13X+39

2. a²+2ab+b²

3 4a²-10a-100

4. 3y² - 22y +35

Step-by-step explanation:

1. (X+13) (X+3)

=x²+(13+3)X+39

=X²+13X+39

2. (a+b) (a+b)

=a²+ab+ab+b²

=a²+2ab+b²

3. (2a+10) (2a-10)

= 4a²-(10-20)2a-100

=4a²-10a-100

4. (y - 5) (3y-7)

= 3y² - (-7-15)y +35

= 3y² - (-7-15)y +35

= 3y² - 22y +35
