Find the least number by which 243 must be divided to make it a perfect<br> square.
yaroslaw [1]

Answer:

Step-by-step explanation:

  • Well I hate to break the news but 243 is not a perfect square. I'll work you through it, 243 is not a perfect square because it is not an even number. an even number must end in (0,2,4,6,8)
  • Step one. Find the square root. the square root of 243 is <em>15.588. </em>
  • Step two Is it a perfect square. No 243 just cant be a perfect square.
  • Hope this helped :)

One root of the quadratic equation x^2 − 2x + m = 0 is 9. If the other root is n, what is n−m?
mote1985 [20]
9^2-2*9+m=0\\&#10;\\&#10;81-18+m=0\\&#10;\\&#10;m=-63

x^{2} -2x-63=0\\&#10;\\&#10;\Delta=(-2)^2-4.1.(-63)=4+252=256\\&#10;\\&#10;x=\frac{2 \pm 16}{2}\\&#10;\\&#10;x_1=\frac{18}{2}=9\\&#10;\\&#10;n=x_2=\frac{-14}{2}=-7\\&#10;\\&#10;n-n=-7-(-63)=-7+63=56
