Solving Quadratic Equations with a lead coefficient of 1 by factoring
Step 1: Set the equation equal to 0 in descending order.
Step 2: The lead coefficient must equal to one to factor this way
Step 3: Factor the trinomial so the value of c, the last term, is the product of two numbers that add to the middle term, b. Write the factors in the form:
(x +/- factor)(x+/-factor)
Step 4. Set each binomial equal to 0.
Step 5: Solve each one step equation for the solution.
