What number is represented by 4x²+17x+2 if x=-2 or if xx=2/3?

-16

15.11

Step-by-step explanation:

We are given an expression which is a function of x and it is 4x² + 17x + 2 ... (1)

We have to find the number which is represented by the above expression when x = - 2 or when x = 2/3.

For, x = - 2, putting - 2 in place of x in the expression (1), we get

4 (-2) ² + 17 (-2) + 2 = 16 - 34 + 2 = - 16 (Answer)

For, x = 2/3, putting 2/3 in place of x in the expression (1), we get

4 (2/3) ² + 17 (2/3) + 2 = 15.11 (Answer)
