Algebra.Com's Answer #33194 by hulamc723(15)![]() ![]() ![]() You can put this solution on YOUR website! -4x=10x^2-24x^3\r \n" ); document.write( "\n" ); document.write( "First, add 4x to both sides so you get 10x^2-24x^3+4x=0 \n" ); document.write( "Then, put the monomials in descending order (-24x^3+10x^2+4x=0) \n" ); document.write( "Now, factor out a 2x form the equation 2x(-12x^2+5x+2)=0 \n" ); document.write( "Now we are going to set up a table to solve for the problem \n" ); document.write( "To do the table, we need to have two sections; The sum of five and the product of -12 and 2 (-24) \n" ); document.write( "To do this we need to find numbers that, when multiplied together, equal -24 and if, when added together, equal five, we know that they are the two numbers that we are going to need to factor the equation!\r \n" ); document.write( "\n" ); document.write( "Sum of 5 Product of -24 \n" ); document.write( "-23(not option) -24,1 \n" ); document.write( "23(not option) 24,-1 \n" ); document.write( "-10(not option) -12,2 \n" ); document.write( "10(not option) 2,-12 \n" ); document.write( "2(not option) 6,-4 \n" ); document.write( "-2(not option) -4,6\r \n" ); document.write( "\n" ); document.write( "Now, since none of the numbers add up to 5, we are going to need to use the quadratic formula \n" ); document.write( "x=-b +or- the square root of b^2-4(a)(c)/2a \n" ); document.write( "now a=-12, b=5, and c=2 \n" ); document.write( "so, -5 +or- the square root of 5^2-4(-12)(2)/2(-12) \n" ); document.write( "-5 +or- the square root of 25+96/-24 \n" ); document.write( "-5 +or- 11/24 \n" ); document.write( "-16/24 and 6/24 or (-2/3 and 1/4) \n" ); document.write( " |
