Algebra.Com's Answer #565 by smartdude17(30)![]() ![]() ![]() You can put this solution on YOUR website! WOW, I've already finished this topic and I'm in seventh grade(lol). Well to find the vertex of a parabola, you use -b/2a. Your equation is this and I'll try to help you solve it from the way you have written it. \n" ); document.write( "y=3(x-2)^2+6 \n" ); document.write( "Now you would clear the parenthesis by: \n" ); document.write( "y=3(x^2-4)+6 this turns into this: \n" ); document.write( "y=3x^2-12+6 \n" ); document.write( "Now you need to simplify it: \n" ); document.write( "y=3x^2-6 \n" ); document.write( "Now you can do the QF (quadratic formula) \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "And this is your scantron answer. Or you could do method #2. \n" ); document.write( " \n" ); document.write( "So this is \n" ); document.write( "And now you M.A.D. it by multiplying 17 and 8 then adding 8 which equals 144/17 and then you multiply it with 1/6 which equals 24/17 and -24/17 \n" ); document.write( " |
