Question

if p(x)=5x-4x³+3 then p(-1) ??
pls answer fast and show me correct answer ..​

Answer 1

Question:-

If p(x)=5x-4x³+3 then p(-1) ??

Solution:-

p (x) = 5x - 4x + 3

p - 1

p=1

p ( 1 ) = 5 ( 1 ) - 4 ( 1 )² + 3

=5 - 4 + 3

=5 - 7

= -2

Final solution:- -2

Answer 2

$\huge { \underline{ \tt{ \red{Question? }}}}$

• If p(x)=5x-4x³+3 then p(-1)?

$\huge { \underline{ \tt{ \green{Answer:- }}}}$

Given:-

• p(x)=5x-4x³+3

To Find:-

• p(-1)

Explaination:-

$\implies \mathtt{p(x)=0}$

$\implies \mathtt{p( - 1)=0}$

$\implies \mathtt{p=1}$

• So, p(x)=5x-4x³+3 :-

$\implies \mathtt{p(x)=5x-4x³+3 :}$

$\implies \mathtt{p(1)=5(1)-4(1)³+3 :}$

$\implies \mathtt{p(1)=5-4+3 }$

$\implies \mathtt{p(1)=2 }$
