To factor, you can first treat it like a single bracket and find the common factor. In this case, the common factor is 3x, so you get
3x(x² + 7x + 12)
Now you can factor the bracket normally, by finding factors of 12 that add up to make 7. The factors would be 3 and 4, so the bracket becomes (x + 3)(x + 4).
This leaves your final answer as
3x(x + 3)(x + 4)

I hope this helps!

What is the slope if the line through the points 2/3, 4/7 and 2/3, 11/7
Umnica [9.8K]

The fromula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points \left(\dfrac{2}{3},\ \dfrac{4}{7}\right) and \left(\dfrac{2}{3},\ \dfrac{11}{7}\right)

Substitute:

m=\dfrac{\frac{11}{7}-\frac{4}{7}}{\frac{2}{3}-\frac{2}{3}}=\dfrac{\frac{7}{7}}{0}\ !!!!

<h3>Answer: slope is undefined.</h3><h3 />

It's a vertical line: x=\dfrac{2}{3}
