solve it fast solve this fast​

Answer 1

Step-by-step explanation:

put value x = 2 in equation

2(2)³ + (2)² -7(2) - 6

= 16 + 4 -14 - 6

= 20-20

=0

hence proved....

Answer 2

Answer:

here we have to show that the following equation will be equal to 0

Step-by-step explanation:

so now,

2(2)^3+(2)^2-7(2)-6=0

2(8)+4-14-6=0

16+4-14-6=0

20-20=0

0=0

Hence x=2

is the zero of the given polynomial
