Question

simplify (2a+5b)(a²+b²)+(3a+4b)(a²-b²)​

Answer 1

Answer:

$5a^3-ab^2+9a^2b+ b^3$

Step-by-step explanation:

$(2a+5b)(a^2+b^2)+(3a+4b)(a^2-b^2)$

$2a *a^2+2a *b^2+5b*a^2+5b*b^2+3a*a^2-3a*b^2+4b*a^2-4b*b^2$

$2a^3+2ab^2+5a^2b+5b^3+3a^3-3ab^2+4a^2b-4b^3$

$2a^3+3a^3+2ab^2-3ab^2+5a^2b+4a^2b+5b^3-4b^3$

$5a^3-ab^2+9a^2b+ b^3$
