3. Use suitable identities to find the following products :
(i) (x + 5) (x + 11)
(ii) (3 + 9) (x - 2)​

Answer 1

Step-by-step explanation:

1)(x+5)(x+11)=x²+11x+5x+55 =x²+16x+55.

2)(3+9)(x-2) =3x-6+9x-18 =12x-24.

1)(2a+3b)(a−b)=2a²+ab−3b²

2)Use the identity `(x+a)(x+b)=x^2+(a+b)x+ab`

I Hope it helps you ☺️
