Question

..Answer The Following Question?​

Answer 1

Answer:

The simplified answer is $x^{4}$

Step-by-step explanation:

Given : to simplify (x² + y²)(x + y)(x - y) + $y^{4}$

Solution : we know (x + y)(x - y) = x² - y² ----------1

Substituting 1 in given expression , we get

(x² + y²)(x + y)(x - y) + $y^{4}$ = (x² + y²) (x² - y²) + $y^{4}$

                                      = ( $x^{4}$ - $y^{4}$ ) + $y^{4}$        

                                      = $x^{4}$
