x2 + 5x - 25 does not have any factors, so if by "do"ing it you mean factoring it, it can not be done.
You can find the x-position of it's vertex by taking it's derivative and solving for zero:
f(x) = x2 + 5x - 25
f'(x) = 2x + 5
0 = 2x + 5
2x = -5
x = -2.5
So the vertex occurs where x = -2.5. The y co-ordinate at that point would be:
2.52 + 5(2.5) - 25
= 6.25 + 12.5 - 25
= 18.75 - 25
= -6.25
So the vertex of this curve occurs at the point (-2.5, -6.25). Because the highest power in the expression has a positive coefficient, we know also that the curve goes upwards.
1x125 5x25
4x-x2 = 2
11-x2=-5 add -11 to both sides: 11-x2-11=-5-11 -x2=-16 divide both sides by -2: (-x2)/(-2)=(-16)/(-2) x=8 If the "x2" was supposed to be "x2", meaning exponentiation, ("x squared") and not "x2", implying multiplication, ("x times two") then we'd get: x2=16 x=±4
x2 × 2x = 2x3

No, they are not equivalent. 2x10 = 20 and 5x25 = 125.
-125
1x125 5x25
In algebra, you cannot solve 5x25 since there is no equation nor an inequality, only an expression.
1x125 5x25
5 x 25 = 125
1X125 or 5X25 or any number of fractions but I won't go into those.
