​

Answer 1

Answer:

Step-by-step explanation:

_____________________________________________________

Simplifying

t^2 + 54 t + 729 = 0

Reorder the terms:

729 + 54 t + t^2 = 0

Solving

729 + 54 t + t^2 = 0

Solving for variable 't'.

Factor a trinomial.

(27 + t)(27 + t) = 0

 

Set the factor '(27 + t)' equal to zero and attempt to solve:

Simplifying

27 + t = 0

Solving

27 + t = 0

Move all terms containing t to the left, all other terms to the right.

Add '-27' to each side of the equation.

27 + -27 + t = 0 + -27

Combine like terms: 27 + -27 = 0

0 + t = 0 + -27

t = 0 + -27

Combine like terms: 0 + -27 = -27

t = -27

Simplifying

t = -27

Set the factor '(27 + t)' equal to zero and attempt to solve:

Simplifying

27 + t = 0

Solving

27 + t = 0

Move all terms containing t to the left, all other terms to the right.

Add '-27' to each side of the equation.

27 + -27 + t = 0 + -27

Combine like terms: 27 + -27 = 0

0 + t = 0 + -27

t = 0 + -27

Combine like terms: 0 + -27 = -27

t = -27

Simplifying

t = -27

Solution

t = {-27, -27}.
