Given that x = 1 - 2i is a root of $\"+x%5E4+-+8x+%2B+23x%5E2+-+42x+%2B30+\"$ , the real solutions to this equation are x = 3 +- sqrt b what is b?
\n" ); document.write( "---------------
\n" ); document.write( "If x = 1 - 2i is a root, then 1 + 2i is also a root.
\n" ); document.write( "(x^2 - 2x + 5) is the product of the 2 complex roots.
\n" ); document.write( "Divide the quartic by that --> a quadratic.
\n" ); document.write( "Solve the quadratic.
