Hello, so here we are given the expression 3x squared plus 6x minus 9.
00:09
So we have a quadratic here, second degree, polynomial.
00:15
But first we look at it, we have three terms, and do we have a common factor? we can factor out of these three terms, and yes, because three goes into everything.
00:24
So we pull out of three, then we say, well, three times x squared, gets us back to 3x squared, three times two x, x is 6x, so plus 2x, and then 3 times negative 3 is going to be negative 9.
00:37
So then we can factor it like so, and then can we factor the inside further? well, possibly.
00:45
So we have three out front...
