Question

i dont undestand this can anyone help​

Answer 1

Answer:

Solve this question by using this identity

[ (a-b) (a+b)=(a2)-(b2)]

Step-by-step explanation:

(4m-7) (4m+7)

{(a-b) (a+b) = (a2)-(b2)}

(4m-7) (4m+7)= (4m)2-(7)2

=16m2-49

Hope this answer helps you!

Answer 2

Step-by-step explanation:

[(a+b) (a-b)] = (a^2) - (b^2)

[(4m -7) (4m +7)] = (4m^2) - (7^2)

16m^2 - 49
