3.5 / 9
(35 / 10) /9
35 / 10 ÷ 9
35 / 10 × 1/9
35 / 90
5 into 35 is 7, and 5 into 90 is 18
7 / 18
So it is 35 / 90 or 7 / 18.
Two lines that cross each other have each pair of angles the same.
2x+6=96 --> x=45
We are given :

Step 1: factor the part inside square root
The function given inside square root is of quadratic form.
So let us try to factorise it using AC method.
Here A*C = 4*25 = 100
so we have to find factors of 100 that add up to give -20.
the two factors are -10 and -10.
Rewriting the function :

=
=
=
Step 2:
Now we take square root of the factorised form

= 
Answer : (2x-5)
