Question

find the value of the polynomial 5x-4x+3.
question 2 x=-1 ​

Answer 1

Answer:

3.5

Step-by-step explanation:

2x=-1

X=-1/2

put the value in 5x-4x+3

X+3

1/2+3

0.5+3

3.5

therefore 3.5 is the ans

Answer 2

Answer:

Given that: a polynomial as

P(x)=5x−4x ^2+3

To find value of polynomail at x=−1 or P(−1)

So we put x=−1 in polynomial,

P(−1)=5×(−1)−4×(−1) ^2+3

P(−1)=−5−4+3

P(−1)=−6

So value of polynomial at x=−1 is −6.
