Hi could someone please tell me if these are correct
Factorise the following
(a)
x^2 + 6x quadratic expression
x(x+6)
(b)
4x^3 - 8x
4x(x^2 -2) cubic expression
They are correct, but depending on what you are expected to do the second one can be further factorised since $\displaystyle (x^2-2)=(x-\sqrt{2})(x+\sqrt{2})$
