Question

Find the value of the polynomial p( x ) =12x^ - 7x + 1, when x=(-2 )​

Answer 1

${\red{\huge{\underline{\mathbb{Answer:-}}}}}$

p{ x} = 12 x²-7x +1 [ given ]

value of p(x) at x = -2

p(-2) = 12 (-2)² -- 7(-2) +1

= 12× 4 +14 +1

= 48+15

= 63

Answer 2

$\huge{ \underline{ \mathfrak{ \green{ \: Answer}}}}$

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

$\boxed{\red{\bold{Given:}}}$

$p(x) = 12x^2 - 7x + 1$

$\boxed{\red{\bold{Just \: put \: x= -2:}}}$

$p(-2) = 12{(-2)}^2 -7(-2) + 1$

$p(-2) = 48 + 14 + 1$

$p(-2) = 63$
