If x squared is not 5, then x is not equal to 5. Do not fall for the trap that the converse is "if x-squared = 25 then x = 5" since that is not a true statement.
( x^2 - 25 ) = ( x + 5 ) ( x - 5 ) <--------------------------
5 squared = 5 x 5 = 25
No.
It is the Cartesian equation of an ellipse.
(x + 5)(x + 5)
x2 + 10y + 25 doesn't factor neatly. If that was x2 + 10x + 25, it would factor to (x + 5)(x + 5) or (X + 5)2
(x^2 - 3x + 5)(x^2 + 3x + 5)
The centre is (-5, 3)
x = 25 / 3squared + 5
x squared +6x +5 is a quadratic expression that can be factored as (x+1)(x+5)
They are +/- 5*sqrt(2)
