The correct Answer is:
To factor the expression \(6a^2 - 13a + 6\), we will follow these steps: ### Step 1: Identify coefficients The given quadratic expression is \(6a^2 - 13a + 6\). Here, the coefficients are: - Coefficient of \(a^2\) (which is \(a^2\)) = 6 - Coefficient of \(a\) (which is \(a\)) = -13 - Constant term = 6 ### Step 2: Multiply the coefficient of \(a^2\) with the constant term We multiply the coefficient of \(a^2\) (which is 6) with the constant term (which is 6): \[ 6 \times 6 = 36 \] ### Step 3: Find two numbers that multiply to 36 and add to -13 Now, we need to find two numbers that multiply to 36 and add up to -13. The two numbers that satisfy this condition are -9 and -4: \[ -9 \times -4 = 36 \quad \text{and} \quad -9 + -4 = -13 \] ### Step 4: Rewrite the middle term using the two numbers We can now rewrite the expression by splitting the middle term (-13a) using -9a and -4a: \[ 6a^2 - 9a - 4a + 6 \] ### Step 5: Group the terms Next, we group the terms into two pairs: \[ (6a^2 - 9a) + (-4a + 6) \] ### Step 6: Factor out the common factors from each group Now, we factor out the common factors from each group: - From \(6a^2 - 9a\), we can factor out \(3a\): \[ 3a(2a - 3) \] - From \(-4a + 6\), we can factor out \(-2\): \[ -2(2a - 3) \] ### Step 7: Combine the factored terms Now, we can combine the factored terms: \[ 3a(2a - 3) - 2(2a - 3) \] Since both terms contain \((2a - 3)\), we can factor that out: \[ (2a - 3)(3a - 2) \] ### Final Answer Thus, the factorization of the expression \(6a^2 - 13a + 6\) is: \[ (2a - 3)(3a - 2) \] ---
