Question

the value of the polynomial 5x_4x2+3 at x=_1 is ​

Answer 1

Step-by-step explanation:

(a) Let p (x) = 5x – 4x2 + 3 …(i)

On putting x = -1 in Eq. (i), we get

p(-1) = 5(-1) -4(-1)2 + 3= - 5 - 4 + 3 = -6

Answer 2

Step-by-step explanation:

• If p(x)=5x-4*2+3

x=-1 [given ]

p(-1)= 5(-1)-8+3

= -5-8+3

= -13+3

= -10

•If p(x) = 5x-4x2+3

x= -1 (given)

p(-1)= 5(-1)-4(-1)2+3

= -5+8+3

= -5+11

= 6

I don't know what you want to say the upper or lower. That's why I give you two answers according to two different polynomial. check what you want to say and than take the answer and ignore the another one.
