1.6x^3y-3x^2y^2 +18x^2y -9xy^2 completly factro the polynomial
6x%5E3y%2B18x%5E2y-3x%5E2y%5E2-9xy%5E2
6x%5E2y%28x%2B3%29-3xy%5E2%28x%2By%29%29
%28x%2By%29%286x%5E2y-3xy%5E2%29
%28x%2By%29%2A3xy%282x-y%29
3xy%28x%2By%29%282x-y%29
2. A rectangle has an area of 2x^2 +5x +3 find possible dimensios for the rectangle Make a sketch of the rectangle
2x%5E2+%2B5x+%2B3 = Area
2x%5E2%2B3x%2B2x%2B3
x%282x%2B3%29%2B1%282x%2B3%29
%28x%2B1%29%282x%2B3%29
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)
