Question

How can i factorize the expression x^3 - 49x?

Answer 1

x^3 -49x

=x(x^2 -49)

=x(x + 7)(x - 7)

Answer 2

First, factor out the x.

So, you get x(x^2-49)

Then, factor (x^2-49)

Result:

x(x-7)(x+7)

Answer 3

Take out x as a common factor:

x(x^2 - 49)

Treat the remainder as difference of squares:

x(x + 7)(x - 7)

Answer 4

Factor out x

x(x^2 - 49), now it's a sq minus a sq so

x(x+7)(x-7)

Answer 5

x^3 - 49x

= x (x^2 - 49)

= x (x + 7) (x - 7)

Answer 6

x(x-7)(x+7)
