Question

8. If are the zeros of the polynomial p(x) = x2 -5x +4 , then the value of . is (a) 4 (b) 5 (c) 9 (d) -1​

Answer 1

Answer:

In the polynomial p(x)=x2-5x+4,

value of x is 4.

Step-by-step explanation:

if x=4 was the answer then

px4=4x2-5x4+4,which would be

4p=-16,which means P=-4

thus 4 isn't the answer.

if x=5 was the answer then

px5=5x2-5x5+4,which would be

5p=-44,which means P=-8.8

thus 5 isn't the answer.

if -1 was the answer then

px-1=-1x2-(-1)x5+4,which would be

-1p=-3, which means that the value of P=undefined,

thus this proves that x=4 is the most valid answer.
