Question

A) (6 - 4x) (6 + 4x)
B) (L2 - m2) (L2 + m2) ​

Answer 1

Answer:

A) 6²-4x²=36-16x²

B) (L2)²-(m2)²=4L²-4m²=4(L²-m²)

Answer 2

Answer:

A) (6 - 4x) (6 + 4x)

Therefore:(a-b)(a+b)=(a)²-(b)²

=(6)²-(4x)²

=36-16x²

B) (L2 - m2) (L2 + m2)

Therefore:(a-b)(a+b)=(a)²-(b)²

(L2)²-(m2)²

L²4-m²4
