Answer 1

Answer:

options is 4

Explanation:

first we will take 5 as common

left is 5(x2 - 25)

now we will use formula a2 - b2 under the bracket

so now we will have 5(x-5)(X+5)

Answer 2

Just Factorise it.

$5x^{2} - 125 \\ = > 5x^{2} - 5 ^{3} \\ = > 5(x ^{2} - 5 ^{2}) \\ = > 5(x + 5)(x - 5) \\ \\ the \: answer \: is \: 5(x + 5)(x - 5)$
