Question

Multiply (3x2 + y2 ) by (x2 + 2y2 )​

Answer 1

Question:

( 3x² + y² ) × ( x² + 2y² )

Step-by-Step Solution:

Multiply the ( x² + 2y² ) by both the terms of ( 3x² + y² ).

⇒ 3x² ( x² + 2y² ) + y² ( x² + 2y² )

After multiplying, we get 4 new values, use DMAS with the values which have same variable.

⇒ 3x⁴ + 6y²x² + x²y² + 2y⁴

To make easy, arrange the values.

⇒ 6y²x² + x²y² + 3x⁴ + 2y⁴

Answer:

⇒ 7y²x² + 3x⁴ + 2y⁴

I hope this helps :)
