(x^2 - 3x + 5)(x^2 + 3x + 5)
3x^2+3x-60=3(x^2+x+20)=3(x+5)(x-4)
NOTE: xx can be written as x^2 i.e. x squared 3x^2 + 16x + 5 = 3 x^2 + x + 15x + 5 (Since 16x = x + 15x) = x ( 3x + 1 ) + 5 ( 3x + 1 ) = ( x + 5 ) ( 3x + 1 ) Therefore the factors are ( x + 5 ) and ( 3x + 1 )
-1
(x - 1)(3x + 5)
X squared - 3x - 10 = 0 (x-5) (x+2) = 0 x - 5 = 0 x + 2 = 0 X= 5 x = -2
2 squared X 3 squared = 5 squared
(x^2 - 3x + 5)(x^2 + 3x + 5)
x^2 + 3x + 2/(-3x) - x^2 - 2=3x-2+2/(-3x)=3x-2-2/(3x)
3x^2+3x-60=3(x^2+x+20)=3(x+5)(x-4)

If that's -5, the answer is (x - 1)(3x + 5) If that's +5, it gets ugly in a hurry.
x^2+2x^2=3x^2
3x^2 -14x +15 = (3x-5)(x-3)
NOTE: xx can be written as x^2 i.e. x squared 3x^2 + 16x + 5 = 3 x^2 + x + 15x + 5 (Since 16x = x + 15x) = x ( 3x + 1 ) + 5 ( 3x + 1 ) = ( x + 5 ) ( 3x + 1 ) Therefore the factors are ( x + 5 ) and ( 3x + 1 )
(3x2 - 6x)/3x = 3x(x-2)/3x = x-2, for x<>0
3x squared - x squared = 2x squared
