\n" ); document.write( " When you have a problem like below how do you solve it? Do you have to solve twice so that you use x both times?\r
\n" ); document.write( "\n" ); document.write( "Find the values of the following expression if x = - 3 and -2
\n" ); document.write( "-x^2-5x-6
\n" ); document.write( " We have to solve it twice taking the values of x as -3 &-2
\n" ); document.write( "1) First taking the value of x = -3 we get -x^2-5x-6 = -(-3)^2-5(-3)-6
\n" ); document.write( " = -(+9)+15-6
\n" ); document.write( " =-9-6+15
\n" ); document.write( " = -15+15
\n" ); document.write( " = 0
\n" ); document.write( " 2)taking the value of x=-2 we get -x^2-5x-6 = -(-2)^2-5(-2)-6
\n" ); document.write( " =-(4)+10-6
\n" ); document.write( " = -4-6+10
\n" ); document.write( " = 0
\n" ); document.write( "
