Question

Q2. Find the value of the polynomial 5x - 4r2 + 3 at x = 0.​

Answer 1

Answer:

the que is not clear , did u write is r^2 or u just mistakenly write it as r^2 but u have to write it ha s x^2 . so I have take 2 cases .

one in which I take it has x^2

second in which I take it has r^2

Step-by-step explanation:

1st case.

when that is x^2

$5x - 4 {x}^{2} + 3$

at x = 0

$5(0) - 4 {(0)}^{2} + 3$

$0 - 0 + 3$

$3$

------------------------------------^^^^^^^------------------------------------

2nd case .

when that is r^2

$5x - 4 {r}^{2} + 3$

at x = 0

$5(0) - 4 {r}^{2} + 3$

$0 - 4 {r}^{2} + 3$

$3 - 4 {r}^{2}$
