    Is the square root of a 2 b 2 a B?

    Originally Answered: Is sqrt (a^2+b^2) = a+b? The answer is no. Sqrt(a^2+ b^2) is not equal to a+b because it will only be equal to a+b when the question asked is sqrt((a+b)^2). The answer would be yes, if either or .

    Is 2a the same as a 2?

    In your case “2a” means that you have variable “a” summed with itself 2 times. And “a^2” means “a” in product with itself twice. It’s simply notation. In the first case, it is addition of a number with itself, in the other case it is multiplication of said number with itself.

  • For the equation x2+lx+m=0.
  • sum of roots is −l and product of roots is m .
  • Therefore, as for x2−22x+105=0 roots are α and β
  • hence α+β=−(−22)=22 and αβ=105.
  • As (α+β)2=(α−β)2+4αβ
  • 222=(α−β)2+4⋅105.
  • or (α−β)2=222−420=484−420=64.
  • and α−β=8.
