Algebra.Com's Answer #48148 by brandonpark2889(31)![]() ![]() ![]() You can put this solution on YOUR website! Solve the following equation for x. Hint: Factor the left hand side. [Do not report answers in decimal – leave them in radical form, and be sure to simplify radicals. \n" ); document.write( "x^2 + 4x + 4 = 7 \n" ); document.write( "I have come up with x = 2 +or- sqrt7. Is this a correct answer??? I would appreciate if someone could let me know howe I am doing. Thanks.\r \n" ); document.write( "\n" ); document.write( "Well... first, of all, the right hand side MUST be 0, if you want to factor it. \n" ); document.write( "So... \n" ); document.write( "up with= \n" ); document.write( "Now think. If x=-3, then it would be (-3+3)(-3-1)=0, right? Simplify that, \n" ); document.write( "then it becomes 0=0. how did I think of x=-3? That's because I thought of \n" ); document.write( "Zero Product Property. Concentrate on (x+3). If you get the opposite of +3, \n" ); document.write( "wouldn't it be -3? and -3+3=0... and 0(-3-1)=0... 0x-4=0... then when you simplify that, the result would be: 0=0. But there are \n" ); document.write( "actually 2 answers. Think of (x-1) now. Repeat this process... x could also \n" ); document.write( "equal 1. So x={-3,1}... not x= 2 +or- sqrt7 :P \n" ); document.write( "--- \n" ); document.write( "I love math. Do you? \n" ); document.write( " \n" ); document.write( " |
