Question

find the value of polynomial 5x-4x2+3 at x=-1​

Answer 1

Answer:

-6

Explanation:

ƒ(x) = 5x - 4x² + 3

⇒ ƒ(-1) = -5 - 4 + 3 = -6

Answer 2

$\huge{\green{\underline{\underline{\tt{Solution:}}}}}$

Given,

☞ x = -1

Let, P(x) = 5x-4x²+3

$→\;{\sf{P(-1) = 5(-1)-4(-1)²+3}}$

$→\;{\sf{P(-1) = -5-4(+1)+3}}$

$→\;{\sf{P(-1) = -5-4+3}}$

$→\;{\sf{P(-1) = -9+3}}$

$➝\;\red{\bf{P(-1) = -6}}$
