Question

factorise 15x2y +9xy2-6xy3
​

Answer 1

Answer:

Will my credit or debit card work in Russia? Visa and Mastercard are widely accepted in Russia. Discover cards are not commonly used. You should be able to withdraw cash at an ATM run by Citibank or Russia Standard bank, but merchants usually do not allow payments using the Discover card.

Answer 2

Step-by-step explanation:

(((3•(x2))•y)+(9x•(y2)))+(2•3xy3)

STEP 2 :

Equation at the end of step2:

(((3 • (x2)) • y) + 32xy2) + (2•3xy3)

STEP 3 :

Equation at the end of step3:

((3x2 • y) + 32xy2) + (2•3xy3)

STEP4:

STEP5:Pulling out like terms

 5.1     Pull out like factors :

   3x2y + 6xy3 + 9xy2  =   3xy • (x + 2y2 + 3y) 

Trying to factor a multi variable polynomial :

 5.2    Factoring    x + 2y2 + 3y 

Try to factor this multi-variable trinomial using trial and error 

 Factorization fails

Final result :

3xy • (x + 2y2 + 3y)
