Answer:
(4x-1)(3x-1)
Explanation:
Given the quadratic expression:

To factorize, follow the steps below.
Step 1: Multiply the coefficient of x² and the constant.

Step 2: Find two numbers that multiply to give 12, and add to give the coefficient of x, -7.
• To do this, list the factors of 12: 1,2,3,4,6,12
,
• Then select your two numbers by observation.

Step 3: Rewrite the middle with those numbers.

Step 4: Factor the first two and last two terms separately.
Ensure that the expression in the brackets is the same.

The factored form is (4x-1)(3x-1).
