Question

Find the value of the polynomial 4x² -5x+3, when x =1/2

Answer 1

$\bold{Answer :}$

Let us take,

f(x) = 4x² - 5x + 3

When x = 1/2,

f (1/2)

= 4 (1/2)² - 5 (1/2) + 3

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

= 1 - 5/2 + 3

= (2 - 5 + 6)/2

= 3/2

Answer 2

Let p(x) = 4x² - 5x + 3

If x = 1/2

Value of p(1/2)

= 4(1/2)² - 5(1/2) + 3

= 4/4 - 5/2 + 3

= 1 - 5/2 + 3

= 4 - 5/2

= 4 - 2.5

= 1.5

Or

p(x) = 3/2
