Question

(2х+1)(4х^2-2х+1) при х 1/2

Answer 1

(2*1/2+1)(4*1/4-2*1/2+1=2*1=2

Answer 2

To evaluate the expression (2x+1)(4x^2-2x+1) when x = 1/2, you need to substitute x with the given value and perform the calculations.

Step 1: Replace x with 1/2 in the expression (2x+1)(4x^2-2x+1):

(2 * (1/2) + 1) * (4 * (1/2)^2 - 2 * (1/2) + 1)

Step 2: Simplify the expression:

(1 + 1) * (4 * (1/4) - 2 * (1/2) + 1)

Step 3: Continue simplifying:

2 * (1 - 1 + 1)

Step 4: More simplification:

2 * 1

Step 5: Final answer:

2

So, when x = 1/2, the expression (2x+1)(4x^2-2x+1) equals 2.
