Question

Find the value of the polynomial x2+2x+7at x=0

Answer 1

$\LARGE{ \underline{\underline{ \pink{ \bf{Required \: answer:}}}}}$

x²+2x+7at= 0

if x= 0

0² + 2 x 0 +7at= 0

7at = 0

a = 0

or

t = 0

Answer 2

Answer:

x2+2x+7at x=0

( put the value of x=0)

0²+2×0+7at=0

7at =0

at = 0/7

at=0

so value of 'a' and 't' is 0
