Solution Steps
To solve the quadratic equation by factoring, we need to express it in the form \((ax + b)(cx + d) = 0\). We will look for two numbers that multiply to \(ac\) (the product of the coefficient of \(x^2\) and the constant term) and add up to \(b\) (the coefficient of \(x\)). Once factored, we can solve for the roots by setting each factor equal to zero.
Step 1: Factor the Quadratic Equation
We start with the quadratic equation:
\[
7x^2 - 20x + 12 = 0
\]
We can factor this equation as:
\[
(7x - 6)(x - 2) = 0
\]
Step 2: Set Each Factor to Zero
Next, we set each factor equal to zero to find the solutions:
\(7x - 6 = 0\)
\(x - 2 = 0\)
Step 3: Solve for \(x\)
Solving the first equation:
\[
7x - 6 = 0 \implies 7x = 6 \implies x = \frac{6}{7}
\]
Solving the second equation:
\[
x - 2 = 0 \implies x = 2
\]
Final Answer
The solutions to the quadratic equation are:
\[
\boxed{\frac{6}{7}, 2}
\]
