Question

If A=a2+6, B=3a2+a+2 and C=a2+4a, then find A+B-C

Answer 1

Answer:

A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it.The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

Answer 2

Explanation:

a2 + 2ab + b2, a2 – 2ab + b2, ... (c) a (3a2 + 6) ... If you were to find some ants outside and ... Sum of a – b + ab, b + c – bc and c – a – ac is.
