Question

Plz help me plz........​

Answer 1

Step-by-step explanation:

for verification....

take a= -2

product of [4a+3/7 a^2] and (7a-a^2)

by putting a= -2 in given question....

[4(-2)+3/7 (-2)^2](7(-2)-(-2)^2)

(-2)^2=4

so,

[-8+3×4/7](-14-4)

[-8+12/7](-18)

(-44/7)(-18)

=792/7

so, answer= 792/7

hope it helps you friend......
