Question

Find the product of
(3y+x³y) (4y³+7x²-5y)​

Answer 1

Answer:

Step-by-step explanation:

[3y+x^3y] [4y^3+7x^2-5y]

= [12y^4]+[21x^2y]-[15y^2]+[4[x^3][y^4]]+[7x^5y]-[5x^3y^2]

Answer 2

♧QUESTION:- Find the product of (3y+x³y) (4y³+7x²-5y)

♧ANSWER:-

◇Here (3y+x³y) both digits will be multiplied with (4y³+7x²-5y) individually.

So,

$\: 3y (4y³+7x²-5y) + x {}^{2} y(4y³+7x²-5y)$

$= 12y {}^{4} + 21x {}^{2} y - 15y {}^{2} + 4x {}^{2} y {}^{4} + 7x {}^{4} y - 5x {}^{2} y {}^{2}$

So, the correct solution of the given equation is

$= 12y {}^{4} + 21x {}^{2} y - 15y {}^{2} + 4x {}^{2} y {}^{4} + 7x {}^{4} y - 5x {}^{2} y {}^{2}$
