You can put this solution on YOUR website!
6bsquared+11b+3 how do i solve?
\n" ); document.write( "---
\n" ); document.write( "You cannot \"solve\" it because it is not an equation.
\n" ); document.write( "You can factor it:
\n" ); document.write( "6b^2 + 11b + 3
\n" ); document.write( "Think of two numbers whose product is 6*3 = 18
\n" ); document.write( "and whose sum is 11.
\n" ); document.write( "The numbers are 9 and 2
\n" ); document.write( "Rewrite the problem but replace 11b by 9b+2b
\n" ); document.write( "---
\n" ); document.write( "6b^2 + 9b + 2b + 3
\n" ); document.write( "Factor the 1st two and the last two terms:
\n" ); document.write( "3b(2b+3) + (2b+3)
\n" ); document.write( "Factor again:
\n" ); document.write( "(2b+3)(3b+1)
\n" ); document.write( "===========================================\r
\n" ); document.write( "\n" ); document.write( "and x squared-18x+81=0
\n" ); document.write( "x^2 - 18x + 81
\n" ); document.write( "Think of two numbers whose product is 81 and sum is -18.
\n" ); document.write( "The numbers are -9 and -9
\n" ); document.write( "------------------------------
\n" ); document.write( "Rewrite the problem:
\n" ); document.write( "x^2 -9x -9x + 81 = 0
\n" ); document.write( "x(x-9) -9(x-9) = 0
\n" ); document.write( "(x-9)(x-9) = 0
\n" ); document.write( "x = 9 with multiplicity 2
\n" ); document.write( "==============================
