Question

plz give me solutions of these 3 questions immediately and there answer should be:-
a) (x^2 + 25x - 900)
b) (x^2 + 5x - 300)
c) (a^2 + 20a + 96)​

Answer 1

what you have asked is not getting

Answer 2

Answer:

Step-by-step explanation:

1. THE IDENTITY THAT SHOULD BE USED FOR BETTER UNDERSTANDING IS : ( x + a ) ( x + b ) = x² + ( a + b )x + ab.

     ⇒x²+(45-20)x+45*(-20) ⇒ x² + 25x - 900 (expanded)

    2. SIMILARLY USE THE SAME IDENTITY AND ,

        ⇒ x² + (-15+20)x + (-15)(20) = x² + 5x - 300 (explained)

    3. AGAIN USE THE IDENTITY AND ,

         ⇒ x² + (8+12)x + 8*12 ⇒ x² + 20x + 96. (expanded)

PLEASE MARK AS THE BRAINLIEST.
