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)
(a4-6a+5)-(a4-3a+4a-6)
by expressing like term
a4-a4=0
-6a-(-3a+4a)=-5a
5-(-6)=11
:we have-5a+11
Answer:
x = 1/3
Step-by-step explanation:
f(x) = -3x^2 + 2x-17
This is in the form
ax^2 +bx+c
a = -3 b = 2 c = -17
The axis of symmetry is at
x = -b/2a
x = -2/ (2*-3)
x = -2/-6
x = 1/3
