Question

Factor the quadratic 27x2-3
(x2 is X squared) please help.

Answer 1

3(3x-1)(3x+1)

Explanation:

27x²-3

You can factor out a 3

3(9x²-1)

Now we can use the difference of perfect squares formula

x²-y²=(x+y)(x-y) which means that 9x²-1=

(3x-1)(3x+1)

put it all together and get

3(3x-1)(3x+1)
