Vedclass · Answer

(C) Let the polynomial be $P(x) = 5x - 4x^2 + 3$.To find the value of the polynomial at $x = -1$,substitute $-1$ for $x$ in the expression:$P(-1) = 5(-1) - 4(-1)^2 + 3$$P(-1) = -5 - 4(1) + 3$$P(-1) = -5 - 4 + 3$$P(-1) = -9 + 3$$P(-1) = -6$Therefore,the correct option is $(c)$.

The value of the polynomial $5x - 4x^2 + 3$ when $x = -1$ is:
