solve equation in exact(surd) form: x(x-3)=4x-3

Quote: Originally Posted by acey4eva solve equation in exact(surd) form: x(x-3)=4x-3 What is the problem? This is a quadratic: x(x-3) = x^2 - 3x, so: x^2 - 3x = 4x - 3, subtract 4x from both sides: x^2 - 7x = -3, add 3 to both sides: x^2 - 7x + 3 =0 So now you use the quadratic formula to solve for x.
