Algebra.Com's Answer #550688 by josgarithmetic(39618)![]() ![]() ![]() You can put this solution on YOUR website! You listed the instructions, so you need to follow those instructions. You will form two LINEAR equations in the variables, A and B, although they are coefficients of a CUBIC equation.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The listed instructions are clear enough for you to know what to do.
