Question

Find the value of the polynomial 5x2 – 4x + 3 at x = 1.​

Answer 1

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.

Answer 2

Answer:

value of polynomials

5x^2-4x+3 at x=1

5.(1)^2-4.1+3

=5-4+3

=8-4

=4
