Answer 2

Hello!

Use the Big X method, since the leading coefficient is greater than 1

Now, let me clarify this a little.

First of all, we should multiply 3 times 18:

54

Now, think of 2 numbers that multiply to 54 and add to 15.

The numbers are 6 and 9.

Now, split the middle:

3x²-6x-9x+54

I hope it helps!

Good luck and enjoy your day!
