Solution for t(t+5)=2t^2+9 equation:


Simplifying
t(t + 5) = 2t2 + 9

Reorder the terms:
t(5 + t) = 2t2 + 9
(5 * t + t * t) = 2t2 + 9
(5t + t2) = 2t2 + 9

Reorder the terms:
5t + t2 = 9 + 2t2

Solving
5t + t2 = 9 + 2t2

Solving for variable 't'.

Reorder the terms:
-9 + 5t + t2 + -2t2 = 9 + 2t2 + -9 + -2t2

Combine like terms: t2 + -2t2 = -1t2
-9 + 5t + -1t2 = 9 + 2t2 + -9 + -2t2

Reorder the terms:
-9 + 5t + -1t2 = 9 + -9 + 2t2 + -2t2

Combine like terms: 9 + -9 = 0
-9 + 5t + -1t2 = 0 + 2t2 + -2t2
-9 + 5t + -1t2 = 2t2 + -2t2

Combine like terms: 2t2 + -2t2 = 0
-9 + 5t + -1t2 = 0

Begin completing the square.  Divide all terms by
-1 the coefficient of the squared term: 

Divide each side by '-1'.
9 + -5t + t2 = 0

Move the constant term to the right:

Add '-9' to each side of the equation.
9 + -5t + -9 + t2 = 0 + -9

Reorder the terms:
9 + -9 + -5t + t2 = 0 + -9

Combine like terms: 9 + -9 = 0
0 + -5t + t2 = 0 + -9
-5t + t2 = 0 + -9

Combine like terms: 0 + -9 = -9
-5t + t2 = -9

The t term is -5t.  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.
-5t + 6.25 + t2 = -9 + 6.25

Reorder the terms:
6.25 + -5t + t2 = -9 + 6.25

Combine like terms: -9 + 6.25 = -2.75
6.25 + -5t + t2 = -2.75

Factor a perfect square on the left side:
(t + -2.5)(t + -2.5) = -2.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
