Answer 2

Answer:

a = 2/7

a = ± 1

Step-by-step explanation:

First of all u need to arrange the polynomial in accordance to their power

So the equation will become   $7a^3 - 2a^2 + 7a - 2$

Now taking a^2 common in first two terms and a in last two terms

The equation becomes

a^2 ( 7a - 2 ) + 1 ( 7a - 2 )

Taking common,

( 7a - 2 ) ( a^2 + 1 )

Now a = 2 / 7                                    [Transportation

        a = ± √1  = ± 1
