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... \"x%5E2%2B4x%2B4=7\". Subtract 7 on each side: \"x%5E2%2B4x%2B4-7=7-7\". It ends
\n" ); document.write( "up with= \"x%5E2%2B4x-3=0\". Now factor this: this turns to: (x+3)(x-1)=0.
\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( "---
