Question

Find out if the values written besides the polynomial, are their zeroes.​

Answer 1

Step-by-step explanation:

$p( \frac{5}{4} ) = 5 \times \frac{5}{4} - 4 \\ = \frac{25}{4} - 4 \\ = 6.25 - 4 = 2.25$

$x = \frac{5}{4}$ is not the zero of this polynomial. if it was then it's result must be 0.
