To solve the equation \(13t^2 - 8t + 1 = -3t^2\), we first need to rearrange the equation to set it to zero.
1. Add \(3t^2\) to both sides:
\[
13t^2 + 3t^2 - 8t + 1 = 0
\]
This simplifies to:
\[
16t^2 - 8t + 1 = 0
\]
Now, we have a standard quadratic equation in the form \(at^2 + bt + c = 0\), where:
- \(a = 16\)
- \(b = -8\)
- \(c = 1\)
Next, we will use the quadratic formula, which is given by:
\[
t = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
\]
2. Calculate the discriminant \(b^2 - 4ac\):
\[
b^2 = (-8)^2 = 64
\]
\[
4ac = 4 \cdot 16 \cdot 1 = 64
\]
Therefore, the discriminant is:
\[
64 - 64 = 0
\]
Since the discriminant is \(0\), there is exactly one solution.
3. Substitute into the quadratic formula:
\[
t = \frac{-(-8) \pm \sqrt{0}}{2 \cdot 16}
\]
This simplifies to:
\[
t = \frac{8}{32} = \frac{1}{4}
\]
Thus, the solution to the equation \(13t^2 - 8t + 1 = -3t^2\) is:
\[
\boxed{\frac{1}{4}}
\]
1. Add \(3t^2\) to both sides:
\[
13t^2 + 3t^2 - 8t + 1 = 0
\]
This simplifies to:
\[
16t^2 - 8t + 1 = 0
\]
Now, we have a standard quadratic equation in the form \(at^2 + bt + c = 0\), where:
- \(a = 16\)
- \(b = -8\)
- \(c = 1\)
Next, we will use the quadratic formula, which is given by:
\[
t = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
\]
2. Calculate the discriminant \(b^2 - 4ac\):
\[
b^2 = (-8)^2 = 64
\]
\[
4ac = 4 \cdot 16 \cdot 1 = 64
\]
Therefore, the discriminant is:
\[
64 - 64 = 0
\]
Since the discriminant is \(0\), there is exactly one solution.

\[
t = \frac{-(-8) \pm \sqrt{0}}{2 \cdot 16}

This simplifies to:
\[

Thus, the solution to the equation \(13t^2 - 8t + 1 = -3t^2\) is:
\[
\boxed{\frac{1}{4}}
\]
