Question

x²+4x+4 find zero of polynomial and verify the difference between sum and products​

Answer 1

4x2+52x−3

=4x2+62x−2x−3

=22x(2x+3)−(2x+3)

=(2x+3)(22x−1)

So, the zeros of the polynomial are 

(2x+3)=0 and (22x−1)=0

       x=2−3 and x=221

       x=2−32 and x=42

Now, the polynomial is  4x2+52
