Question

find the value of the polynomial 5 x -4 x square +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:

p(-1)=5(-1)-4(-1)²+3

= -5-4+3

= -9+3

= -6
