Ax^2+Bx+C=0 \n" ); document.write( "the roots are 1+/- i sqrt(7) \n" ); document.write( "in the quadratic formula, one divides by 2a, so let a=1 and we will be dividing by 2 \n" ); document.write( "if we do that, the numerator must be 2+/-2i sqrt(7) \n" ); document.write( "this is 2+/- 2sqrt (-7); note that the sqrt term is sqrt (-28), because that may be broken down into sqrt(4)*sqrt(-7) which is 2*i sqrt(7) \n" ); document.write( "b=-2 \n" ); document.write( "b^2-4ac=-28, a=1, b=-2, so find c \n" ); document.write( "4-4(1)(c)=-28 \n" ); document.write( "-4c=-32 \n" ); document.write( "c=8 \n" ); document.write( "x^2-2x+8 \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
