Question

( x+y) : ( x - y ), ( x² + y²): ( x+y )², ( x² - y²)² : ( x⁴ - y⁴)​

Answer 1

Step-by-step explanation:

(x+y):(x-y) = x(x-y)+y(x-y)=x²-xy+xy-y²=x²-y² ans. (x²+y²):(x+y)²=(x²+y²): (x²+2xy+y²)=x²(x²+2xy+y²)+y²(x²+2xy+y²) =x⁴+2x³y+x²y²+x²y²+2xy³+y⁴= x⁴+2x³y+2x²y²+2xy³+y⁴ Ans. bhai last wala bhi 2 nd wala jaisa he rule hein .mera camera kharab hai isliye waise dena pada
