Question

Which of the following shows a factor of 100b^2 - 144a^4?
A.10b - 12a
B.10b+ 12a
C.10b + 12a^2
D.50b - 72a^2

Answer 1

Thx

Answer 3

C

because...

\[\LARGE 100b^2\longrightarrow (10b)^2 , 144a^4\longrightarrow (12a^2)^2\]

So we have:

\[\LARGE (10b)^2-(12a^2)^2=\left[(10b)-(12a^2)\right] \cdot \left[(10b)+(12a^2)\right]\]

So the answer is C
