Answer:
 
Step-by-step explanation:
We see that the two terms share an x, so we can pull that out:

Now notice that we have a difference of squares ( ). Given a difference of squares,
). Given a difference of squares,  , this can always be factored into
, this can always be factored into  . We can use this in this case:
. We can use this in this case:  .
.
So, our final factorized form is:  .
.
Hope this helps!

Answer:
a) Fx=-5N  Fy=-5*sqrt(3) N   b) Fx= 5*sqrt(3) N    Fy=-5N
c) Fx=-5*sqrt(2) N    Fy=-5*sqrt(2)   N
Step-by-step explanation:
The arrow's F ( weight) component on axle x  is Fx= F*sinA  and on axle y is
Fy=F*cosA
a) The x component and y component both are opposite directed to axle x and axle y accordingly.  So both components are negative.
So Fx = - 10*sin(30)= -5 N      Fy= -10*cos(30)= -10*sqrt(3)/2= -5*sqrt (3) N
b) Now the x component  is co directed to axle x , and y component is opposite directed to axle y.
So x component is positive and y components is negative
 So Fx = 10*sin(60)= 5*sqrt(3) N       Fy= -10*cos(60)= -10*1/2= -5 N
c)The x component and y component both are opposite directed to axle x and axle y accordingly.  So both components are negative.
So Fx = - 10*sin(45)= -5*sqrt(2)  N    
  Fy= -10*cos(45)= -10*sqrt(2)/2= -5*sqrt (2) N
