Algebra.Com's Answer #20540 by Nate(3500)![]() ![]() ![]() You can put this solution on YOUR website! To find values of c you need values for x, but we can simplify: \n" ); document.write( "x^2+4x+c=0 \n" ); document.write( "(x^2+4x)=-c \n" ); document.write( "(x + 2)^2 = 4 - c \n" ); document.write( "4 - (x + 2)^2 = c \n" ); document.write( "The answer for c depends on the value for x. With the information you provided, we can assume that any number can be used for x.... so infinitely many. \n" ); document.write( " |
