Question

Find the values for aaa and bbb that would make the equality true. -2y(y^2-6y-3) = ay^3+12y^2+by−2y(y 2 −6y−3)=ay 3 +12y 2 +by

Answer 1

a= -2 and b= 6

Step-by-step explanation:

-2y(y^2-6y -3) = ay^3 + 12y^2 + by

-2y^3 + 12y^2 + 6y = ay^3 + 12y^2 + by

-2 y^3 + 6y = ay^3 + by

compare both sides-

• -2y^3 = ay^3 ,then a =-3
• 6y = by , then b= 6
