Question 478744
1.6x^3y-3x^2y^2 +18x^2y -9xy^2 completly factro the polynomial
{{{6x^3y+18x^2y-3x^2y^2-9xy^2}}}

{{{6x^2y(x+3)-3xy^2(x+y))}}}

{{{(x+y)(6x^2y-3xy^2)}}}

{{{(x+y)*3xy(2x-y)}}}

{{{3xy(x+y)(2x-y)}}}

2. A rectangle has an area of 2x^2 +5x +3 find possible dimensios for the rectangle Make a sketch of the rectangle

{{{2x^2 +5x +3}}} = Area

{{{2x^2+3x+2x+3}}}

{{{x(2x+3)+1(2x+3)}}}

{{{(x+1)(2x+3)}}}

Length = (2x+3)
Width = (x+1)
3. A sqaure has an area of 9x^2+30x+25 find the length of a side make a sketch of the square

9x^2+30x+25
This is a perfect square
(3x+5)^2= Area

The sides are (3x+5)
