To solve the equation \( 8v^2 - 18v + 9 = 0 \), we can use the factoring method.
First, let's look for two numbers that multiply to \( 8 \times 9 = 72 \) and add up to \( -18 \).
The factoring approach will involve rewriting the equation in the form:
\[ (Av + B)(Cv + D) = 0 \]
where \( A \times C = 8 \) and \( B \times D = 9 \).
After checking different combinations, we can factor the quadratic:
Rewrite the equation:
\[ 8v^2 - 12v - 6v + 9 = 0 \]
Group the terms:
\[ (8v^2 - 12v) + (-6v + 9) = 0 \]
Factoring each group yields:
\[ 4v(2v - 3) - 3(2v - 3) = 0 \]
Now, factor out the common factor \( (2v - 3) \):
\[ (4v - 3)(2v - 3) = 0 \]
Setting each factor to zero gives us the possible values for \( v \):
-
\( 4v - 3 = 0 \) \[ 4v = 3 \] \[ v = \frac{3}{4} \]
-
\( 2v - 3 = 0 \) \[ 2v = 3 \] \[ v = \frac{3}{2} \]
Thus, the solutions to the equation \( 8v^2 - 18v + 9 = 0 \) are:
\[ v = \frac{3}{4}, \frac{3}{2} \]
So the final answer is:
\[ v = \frac{3}{4}, \frac{3}{2} \]
