$x^2-4x+4-4=3$
Learn how to solve integrals of exponential functions problems step by step online. Solve the quadratic equation x^2-4x=3. Factor the polynomial x^2-4x. Add and subtract \left(\frac{b}{2}\right)^2, replacing b by it's value -4. Now, we can factor x^2+-4x+4 as a squared binomial of the form \left(x+\frac{b}{2}\right)^2. The square root of 4 is . Multiply -1 times 2.
Final Answer
$x=4.645751,\:x=-0.645751$
