Question

What is the answer for 9x² + 3xy - 12x - 4y ​

Answer 1

Answer:

${ \tt{9 {x}^{2} + 3xy - 12x - 4y }} \\ ={ \tt{x(9x + 3y - 12) - 4y}}$

Answer 2

Answer:

(3x + y)(3x - 4)

Step-by-step explanation:

9x² + 3xy - 12x - 4y ​=

There is no common factor in the 4 terms.

Since there are 4 terms, we try factoring by grouping.

Find a common factor in the first two terms, and find a common factor in the last two terms.

= 3x(3x + y) - 4(3x + y)

Now factor out the common factor 3x + y.

= (3x + y)(3x - 4)
