You can put this solution on YOUR website!
f(x) = -5x+3, g(x) = x^2+2x Move all the terms to the left side:
\n" ); document.write( "x^2+2x-5x+3 = 0 Combine like terms:
\n" ); document.write( "x^2-3x+3 = 0
\n" ); document.write( "Now we have a quadratic equation in the form ax^2+bx+c, so i'll solve it by using the quadratic formula:
\n" ); document.write( "x = -(-3÷2)+-√(-3÷2)2-3
\n" ); document.write( "Run the calculations and you get:
\n" ); document.write( "x = 1.5±0.866025403784i This calculation has no real solution. Usually you don't have to go beyond this point.
