\n" );
document.write( "\n" );
document.write( "that's the square root of x^2 minus 10x plus 25. with the a negitive symbol on the outside of the square root sign. I think i need to factor this but i dont think i did it right... please help \n" );

Algebra.Com's Answer #19966 by priya(51)![]() ![]() ![]() You can put this solution on YOUR website! SO THE NEGATIVE SIGN IS ON THE OUTSIDE OF THE SQRT.\r \n" ); document.write( "\n" ); document.write( "then the expression is -sqrt(x^2-10x+25)\r \n" ); document.write( "\n" ); document.write( " first try to simplify the expression inside the rt. \n" ); document.write( " \n" ); document.write( " x^2-10x+25\r \n" ); document.write( "\n" ); document.write( "there is a simple procedure to find the values of x and is given below \n" ); document.write( "(factorise 25 and find 2 values of x,such that the product of \n" ); document.write( "the 2 values gives u 25 and the sum of the values are -10,if u cannot do that u have to follow this formula \n" ); document.write( "\n" ); document.write( "but in this case u get values as -5 and -5,when u multiply they give u 25 and when u add them,they give u -10.\r \n" ); document.write( "\n" ); document.write( "so this is written as \n" ); document.write( " (x-5) and (x-5) ,put this value in the expression in the place of \n" ); document.write( " x^2-10x+25. \r \n" ); document.write( "\n" ); document.write( " therefore we get, - sqrt((x-5)(x-5)) \r \n" ); document.write( "\n" ); document.write( " the answer is -(x-5) (because sqrt(a^2)=a,here sqrt((x-5)^2)=(x-5))\r \n" ); document.write( "\n" ); document.write( " VISIT MY SITE(CLICK ME) TO LEARN MATHS ONLINE!! \n" ); document.write( "PRIYA \n" ); document.write( " |
