Solution for 5t^2-14t+100=0 equation:


Simplifying
5t2 + -14t + 100 = 0

Reorder the terms:
100 + -14t + 5t2 = 0

Solving
100 + -14t + 5t2 = 0

Solving for variable 't'.

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

Divide each side by '5'.
20 + -2.8t + t2 = 0

Move the constant term to the right:

Add '-20' to each side of the equation.
20 + -2.8t + -20 + t2 = 0 + -20

Reorder the terms:
20 + -20 + -2.8t + t2 = 0 + -20

Combine like terms: 20 + -20 = 0
0 + -2.8t + t2 = 0 + -20
-2.8t + t2 = 0 + -20

Combine like terms: 0 + -20 = -20
-2.8t + t2 = -20

The t term is -2.8t.  Take half its coefficient (-1.4).
Square it (1.96) and add it to both sides.

Add '1.96' to each side of the equation.
-2.8t + 1.96 + t2 = -20 + 1.96

Reorder the terms:
1.96 + -2.8t + t2 = -20 + 1.96

Combine like terms: -20 + 1.96 = -18.04
1.96 + -2.8t + t2 = -18.04

Factor a perfect square on the left side:
(t + -1.4)(t + -1.4) = -18.04

Can't calculate square root of the right side.

The solution to this equation could not be determined.
