Question

Factories the following expression 8x^2 + 72x^2 y^2 + 162y^4​

Answer 1

• step by step : ---

• 8x⁴ + 72x²y² + 162y⁴

• ( Whole equeation Divided by 2)

• 4x⁴ + 36x²y² + 81y⁴

• we know that,

• ( a + b )² = a² + 2.a.b + b²

• ( 2x² )² + 2.2x².9y² + ( 9y² ) ²

• ( 2x² + 9y² )²

• ( 2x² +9y² ) . ( 2x² + 9y² ) (Ans.)
