Question

find the coefficient of polynomial 4x²-5x+9, when x=1/2. ​

Answer 1

Answer:

$4 {x}^{2} - 5x + 9$

$4 \times \frac{1}{2} \times \frac{1}{2 } - 5 \times \frac{1}{2} + 9$

$4 \times \frac{1}{4} - \frac{5}{2} + 9$

$\frac{4}{4} - \frac{5}{2} + 9$

Step-by-step explanation:

$\frac{1}{1} - \frac{5}{2} + \frac{9}{1}$

$\frac{1}{1} - \frac{5}{2} + \frac{18}{2}$

$\frac{23}{2} - \frac{1}{1}$

$\frac{23}{2} - \frac{2}{2}$

$\frac{21}{2}$
