Question

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

Answer 1

-16

15.11

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)
