(t-1)(-2t-3)=

Solution for (t-1)(-2t-3)= equation:

Simplifying
(t + -1)(-2t + -3) = 0

Reorder the terms:
(-1 + t)(-2t + -3) = 0

Reorder the terms:
(-1 + t)(-3 + -2t) = 0

Multiply (-1 + t) * (-3 + -2t)
(-1(-3 + -2t) + t(-3 + -2t)) = 0
((-3 * -1 + -2t * -1) + t(-3 + -2t)) = 0
((3 + 2t) + t(-3 + -2t)) = 0
(3 + 2t + (-3 * t + -2t * t)) = 0
(3 + 2t + (-3t + -2t2)) = 0

Combine like terms: 2t + -3t = -1t
(3 + -1t + -2t2) = 0

Solving
3 + -1t + -2t2 = 0

Solving for variable 't'.

Factor a trinomial.

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

Add '-3' to each side of the equation.
3 + -3 + 2t = 0 + -3

Combine like terms: 3 + -3 = 0
0 + 2t = 0 + -3
2t = 0 + -3

Combine like terms: 0 + -3 = -3
2t = -3

Divide each side by '2'.
t = -1.5

Simplifying
t = -1.5
Solution
t = {1, -1.5}
