i am up to this point in my problem but i don't know what to do next with it can someone show me.
Directions: Simplify by combining like terms
x radical(18) minus 3radical(8x^2)
these are the steps that i've done so far.
= x radical (2*9) 3radical (2*4*x^2)
= x radical (2) * radical (9)  3 radical (2) * radical (4) * radical (x^2)
=x * radical (2) * 3  3*radical (2) * 2 * x
from here i do not know can someone help me finish.
You are so close
=x*√2*33*√2*2*x
=3x√26x√2
=3x√2 or 3√2*x
