Question

20 points! Simplify: 2y(2y+3yx^{2} )-y^{2} (3-y) please show work!

Answer 1

8x2y - 6x2 - 8xy2 - y2

Explanation:

Equation at the end of step 1 :

(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-(3•(y2)))-((((x2)+(y2))+(8x•(y2)))-3y2)

Step 2 :

Equation at the end of step 2 :

(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-(3•(y2)))-((((x2)+(y2))+23xy2)-3y2)

Step 3 :

Equation at the end of step 3 :

(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-3y2)-(x2+8xy2-2y2)

Step 4 :

Equation at the end of step 4 :

(((((5•(x2))•y)-(5•(x2)))+3x2y)-3y2)-(x2+8xy2-2y2)

Step 5 :

Equation at the end of step 5 :

(((((5•(x2))•y)-5x2)+3x2y)-3y2)-(x2+8xy2-2y2)

Step 6 :

Equation at the end of step 6 :

((((5x2•y)-5x2)+3x2y)-3y2)-(x2+8xy2-2y2)

Step 7 :

Final result :

8x2y - 6x2 - 8xy2 - y2
