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

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

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

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

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

Multiply (1 + 2t) * (-3 + t)
(1(-3 + t) + 2t * (-3 + t)) = 0
((-3 * 1 + t * 1) + 2t * (-3 + t)) = 0
((-3 + 1t) + 2t * (-3 + t)) = 0
(-3 + 1t + (-3 * 2t + t * 2t)) = 0
(-3 + 1t + (-6t + 2t2)) = 0

Combine like terms: 1t + -6t = -5t
(-3 + -5t + 2t2) = 0

Solving
-3 + -5t + 2t2 = 0

Solving for variable 't'.

-1t = 0 + -3

Combine like terms: 0 + -3 = -3
-1t = -3

Divide each side by '-1'.
t = 3

Simplifying
t = 3
Solution
t = {-0.5, 3}
