<h3>Solving quadratic equations</h3>From the question, we are to solve the given quadratic equation
Two methods Fred could use to solve the equation are
- The completing the square method
- The formula method
The given quadratic function is
f(x) = 4x² + 16x+9
Now, we are to solve f(x) = 0 for x
That is,
4x² + 16x+9 = 0
Using the formula method to solve the equation
In the equation,
a = 4, b = 16, and c = 9
∴
OR
OR
x = -0.6771 OR x = - 3.3229
x ≅ -0.7 OR x ≅ - 3.3
Hence, the solution for the function is x ≅ -0.7 OR x ≅ - 3.3
