Question

If ax² + 2a²x+b² is divisible by x+a , prove that a= b or a² + ab+b² = 0​

Answer 1

Answer:

I don't no.............

Answer 2

Step-by-step explanation:

since ax²+2a²x+b³ is divisible

byx+a,f(-a)=0.

therefore a(-a)²+2a²×-a+b³=0.

" -a³+b³=0.

" (b-a) ( b²+ab+a²)=0.

" b=a or b²+ab+a²=0.
