Question

If A=x² - y³ , B = x² + y³ then find A + B.​

Answer 1

Answer:

$A = {x}^{2} - {y}^{3} \\ B = {x}^{2} + {y}^{3} \\ \\ ATQ = > \\ \\ A+ B \\→ ( {x}^{2} - {y}^{3} ) + ( {x}^{2} + {y}^{3} ) \\ \\→ {x}^{2} - { \cancel {{y}^{3} }} + {x}^{2} + { \cancel {{y}^{3}} } \\ \\ →{x}^{2} + {x}^{2} \\ \\ = > {2x}^{2}$
