# Program won't accept $2(-5x+1)(-4x+3)$ as an answer to factoring $40x^2-38x+6$.

Here is what I have done so far:

$$2(20x^2-19x+3)$$ //factored the GCF

$$60x²$$//Multiplied $$3$$ into $$20x²$$

$$-15x -4x$$ //These two numbers add into $$-19x$$, and multiply into $$60x²$$

$$2((20x^2-15x)(-4x+3))$$ //Put it into form again.

$$2(-5x(-4x+3)1(-4x+3))$$ //Factored the GCF out of each grouping.

$$2(-5x+1)(-4x+3)$$ //Reformatted to try and get the final answer.

I am stuck on this step.

Any help would be greatly appreciated. I am a high school math student, so I am obviously not an expert in this stuff. I just want to understand what I did wrong or what the computer wants and learn from it.

• Your answer is correct. It's a problem with the program. Try multiplying each of the last two factors by $-1$ and see if it will accept that. Oct 28 '20 at 15:22

$$40x^2-38x+6=2(5x-1)(4x-3)$$
