Factor 5x4 - 30x2 - 135. 5(x2+ 9)(x2- 3) *********** 5(x - 3)(x + 3)(x2- 3) I think it is the one with ******* 5(x - 3)(x + 3)(x2+ 3)
no sorry,its the last one \(5(x - 3)(x + 3)(x^2+ 3)\)
\[5(x^4 - 6x^2 - 27) = 5(x^4 - 9x^2 + 3x^2 - 27)\]
I think you can group the terms and factor.
so it is the last one
this is an equation reducible to a quadratic take 5 as the common factor and then you have \[5(x^4 - 6x^2 - 27)\] which can be treated as \[5((x^2)^2 - 6(x^2) - 27)\]
will u help me again all of u
