You can put this solution on YOUR website!
there are several ways to solve this ,,here i am doing which can be understand easily by you through this medium..
2 root of 18 - 6 root of 18
take (root of 18) common and you get
= 2 - 6 (root of 18 )
= -4 (root of 18)
now open brackets and you get answer
= -4 root of 18
for better understanding ,,,see below
......its is solved in the same ways as we solve..
= 2x-6x....here think that x stands for root of 18
= -4x,,,,you can also calculate your above answer..
hope this will help you
