Question

Factor completely.
6x²+ 3x - 63

Answer 1

Look at the first and last terms, find their factors and try to put them in two brackets.
I will give u the factors to use and u can try to do it urself.
the factors that need to be used are 9 and 7 and the brackets will be >> (3x )(2x )

Answer 2

(3x )(2x )

Answer 3

an alternate method would be to take out 3 first (since it is common to each term)

3(2x + x - 21)

now break down the middle terms

3(2x - 6x + 7x - 21)

now you can proceed to good ol' factoring ;)
