Exercise
$4x^2+x-2$
Step-by-step Solution
Learn how to solve problems step by step online. Factor the expression 4x^2+x+-2. Use the complete the square method to factor the trinomial of the form ax^2+bx+c. Take common factor a (4) to all terms. Add and subtract \displaystyle\left(\frac{b}{2a}\right)^2. Factor the perfect square trinomial x^2+\frac{1}{4}x+\frac{1}{64}. Solve the product 4\left(\left(x+\frac{1}{8}\right)^2-\frac{33}{64}\right).
Factor the expression 4x^2+x+-2
Final answer to the exercise
