The problem is 2x^2-3x-5=0 \n" ); document.write( "There are 6 steps and I have gotten to step 3 \n" ); document.write( "Step 1 2x^2-3x=5 \n" ); document.write( "Question: Why do you multiply by 4? \n" ); document.write( "Step 2 8x^2-12x=20 \n" ); document.write( "Step 3 -3 is the original x term, therefore: \n" ); document.write( "8x^2-12x+9=29 \n" ); document.write( "----- \n" ); document.write( "I don't think your 3rd step is correct. \n" ); document.write( "According to your step 4 you need to complete the \n" ); document.write( "square in step 3. That would be as follows: \n" ); document.write( "8x^2-12x = 20 \n" ); document.write( "x^2 - (3/2)x = (5/2) \n" ); document.write( "Competing the square you would get: \n" ); document.write( "x^2 - (3/2)x + (3/4)^2 = (5/2) + (3/4)^2 \n" ); document.write( "Now you are ready to factor and then take the square root of both sides. \n" ); document.write( "----------------------- \n" ); document.write( "Step 4, now I am to take the square root of each side. \n" ); document.write( "(x-(3/4))^2 = (49/16) \n" ); document.write( "(x-(3/4)) = +-7/4 \n" ); document.write( "x = (7/4)+(3/4) or x = -(7/4)+(3/4) \n" ); document.write( "x = 5/2 or x = -1 \n" ); document.write( "====================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "------------------------------ \n" ); document.write( " |
