Solution for r^2-5r+24=0 equation:


Simplifying
r2 + -5r + 24 = 0

Reorder the terms:
24 + -5r + r2 = 0

Solving
24 + -5r + r2 = 0

Solving for variable 'r'.

Begin completing the square.

Move the constant term to the right:

Add '-24' to each side of the equation.
24 + -5r + -24 + r2 = 0 + -24

Reorder the terms:
24 + -24 + -5r + r2 = 0 + -24

Combine like terms: 24 + -24 = 0
0 + -5r + r2 = 0 + -24
-5r + r2 = 0 + -24

Combine like terms: 0 + -24 = -24
-5r + r2 = -24

The r term is -5r.  Take half its coefficient (-2.5).
Square it (6.25) and add it to both sides.

Add '6.25' to each side of the equation.
-5r + 6.25 + r2 = -24 + 6.25

Reorder the terms:
6.25 + -5r + r2 = -24 + 6.25

Combine like terms: -24 + 6.25 = -17.75
6.25 + -5r + r2 = -17.75

Factor a perfect square on the left side:
(r + -2.5)(r + -2.5) = -17.75

Can't calculate square root of the right side.
