Question

In the polynomial P(x)=4x²+24x+11, what number should we take as x to get P(x)=0​

Answer 1

Answer:

Take x = $-\frac{1}{2}$   or you can take x = $\frac{-11}{2}$

I got this x value by factorization method

Step-by-step explanation:

Given :

P(x)=4x²+24x+11

Let x = $-\frac{1}{2}$

P($-\frac{1}{2}$) = 4 ($\frac{-1}{2}$)² + 24 ($\frac{-1}{2}$) + 11

         = 4($\frac{1}{4}$) + (- 12) + 11

         = 1 - 12 + 11

         = 12 - 12

P($-\frac{1}{2}$) = 0
