Learn how to solve completing the square problems step by step online. Solve the equation y=3x^2+5x+8. Use the complete the square method to factor the trinomial of the form ax^2+bx+c. Take common factor a (3) to all terms. Add and subtract \displaystyle\left(\frac{b}{2a}\right)^2. Factor the perfect square trinomial x^2+\frac{5}{3}x+\frac{25}{36}. The least common multiple (LCM) of a sum of algebraic fractions consists of the product of the common factors with the greatest exponent, and the uncommon factors.

Final answer to the problem

$y=\frac{36\left(x+\frac{5}{6}\right)^2+71}{12}$
