You can put this solution on YOUR website!
This isn't an equation, if you meant factor:
\n" ); document.write( "\"2a%5E2%964a%9670\" factor out the GCF 2
\n" ); document.write( "\"2%28a%5E2-2a-35%29\"
\n" ); document.write( "2(a___)(a____) the blank needs to be filled with two numbers that = -35 when multiplied and add to give you -2. -7*5=-35 and -7+5=-2
\n" ); document.write( "\"highlight%282%28a-7%29%28a%2B5%29%29\"
\n" ); document.write( "If you really meant to type 2a^2-4a-70=0, we can now solve it.
\n" ); document.write( "\"2%28a-7%29%28a%2B5%29=0\"
\n" ); document.write( "\"2%28a-7%29%28a%2B5%29%2F2=0%2F2\"
\n" ); document.write( "\"%28a-7%29%28a%2B5%29=0\"
\n" ); document.write( "a-7=0 and a+5=0
\n" ); document.write( "a=7 and a=-5
\n" ); document.write( "Happy Calculating!!!
