The
1. Find the value of the polynomial 4x2 - 5x+3. at
(iv) x=1/2
​

Answer 1

Answer:

3/2

Step-by-step explanation:

Given polynomial is 4x2 - 5x+3

If x= 1/2 then 4(1/2)^2-5(1/2)+3

=>4×1/4-5/2+3

=>4/4-5/2+3

=>1-5/2+3

=>(2-5+6)/2

=>(8-5)/2

=>3/2

The value of the given polynomial if x=1/2 is 3/2

Answer 2

Explation -We need to find value of polynomial at x=1/2

Replace x to 1/2, we get

p(x)=4x^2 -5x+3

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

p (1/2)=4 - 2.5 +3

p (1/2)=4.5
