One root of the quadratic equation x^2 − 2x + m = 0 is 9. If the other root is n, what is n−m?

Answers

Answer 1

Answer: $9^2-2*9+m=0\n \n 81-18+m=0\n \n m=-63$

$x^(2) -2x-63=0\n \n \Delta=(-2)^2-4.1.(-63)=4+252=256\n \n x=(2 \pm 16)/(2)\n \n x_1=(18)/(2)=9\n \n n=x_2=(-14)/(2)=-7\n \n n-n=-7-(-63)=-7+63=56$
