Question

The value of polynomial 5x-4x^2+3 at
X=-1 is
1. 6
2. -6
3. 2
4. 12​

Answer 1

${ \huge{ \pink{ \underline{ \underline{ \red{ \mathbb{ \bigstar{ \purple{solution}}}}}}}}}$

ʟᴇᴛ , ᴩ (x) = 5x-4x²+3

ᴩ(-1)=5(-1)-4(-1)²+3

ᴩ(-1)=-5-4+3

ᴩ(-1)=-6

ᴀɴꜱᴡᴇʀ :- -6

Answer 2

${ \huge{ \pink{ \underline{ \underline{ \red{ \mathbb{ \bigstar{ \purple{solution}}}}}}}}}$

ʟᴇᴛ , ᴩ (x) = 5x-4x²+3

ᴩ(-1)=5(-1)-4(-1)²+3

ᴩ(-1)=-5-4+3

ᴩ(-1)=-6
