Answer 2

To solve the equation, let's simplify the expression:

48t^2 - (12t - 4) * (4t + 1) = -2

First, distribute the terms inside the parentheses:

48t^2 - (48t^2 + 12t - 16t - 4) = -2

Simplify further by combining like terms:

48t^2 - 48t^2 - 12t + 16t + 4 = -2

-12t + 16t + 4 = -2

4t + 4 = -2

Subtract 4 from both sides:

4t = -2 - 4

4t = -6

Divide both sides by 4:

t = -6/4

Simplifying the fraction:

t = -3/2

Therefore, the solution to the equation is t = -3/2, which can be expressed as a decimal fraction as t = -1.5.
