Question

If x=1/2, then find value of polynomial
4x²-5x+3

Answer 1

Answer : 3/2

Step by step explanation:

Given polynomial:

4x² - 5x + 3

Value of x = 1/2

Putting the value of x in the given eq.

» 4 (1/2)² - 5 × 1/2 + 3

» 4 × 1/4 - 5/2 + 3

» 1 - 5/2 + 3

» (2 - 5 + 6)/2

» (2 + 1)/2

» 3/2

Hence, the value of the given polynomial is 3/2.

Answer 2

Answer:

Given x=½

f(x) = 4x²-5x+3

By putting the value of x in the Quadratic polynomial we get

4x²-5x+3

4(½)²-5(½)+3

4×¼-5/2+3

4/4-5/2+3

1-5/2+3

taking 2 lCM

(2-5+6)/2

(-3+6)/2

3/2 .....
