# How do you factor #18x^2-27x+4#?

##### 2 Answers

#### Explanation:

One technique is to employ this handy formula:

You will get;

Rearrange them;

Multiply them;

Voila!

I recommend this technique for **large coefficients** of **different possible ways** to factor 18:

1 and 18, 2 and 9, 6 and 3.

This will save you the time from trial and error especially for even bigger coefficients.

Solve

Ans: (6x - 1)(3x - 4)

#### Explanation:

Use the new AC Method. y = 18(x - p)(x - q)

Converted trinomial:

p' and q' have same sign.

Factor pairs of (72) --> (2, 36)(3, 24) . This sum is 27 = -b.

Change the sum to b. Then, p' = -3 and q' = -24.

Therefor.
