Answer:
4(a - 2)(a - 1)
Step-by-step explanation:
4a^2 - 12a + 8 =
First, factor out a common factor from all terms.
= 4(a^2 - 3a + 2)
To factor a^2 - 3a + 2, you need two numbers whose product is 2 and whose sum is -3. Since the product is a positive number, 2, the two numbers are either both positive or both negative. Since the sum is negative, -3, then both numbers must be negative. The two numbers are -1 and -2.
= 4(a - 2)(a - 1)
