Question 56317
Hi lackinmath,
:
Completly factor the following:
{{{3x^3y-12x^2y+9xy}}}
{{{3xy(x^2)+(3xy)(-4x)+3xy(3)}}}
{{{3xy(x^2-4x+3)}}}
3xy(x___)(x____)
We need to fill the blanks with two numbers that multiply together to give you c=+3, but add together to give you b=-4.
-1*-3=3 and -3+-1=-4
{{{highlight(3xy(x-1)(x-3))}}}
Keep Calculating and you won't be lackinmath!!!
