The first step is to write the equation as quadratic = linear. Then you just take all values to one side so that you remain with 0 on the other. Next solve the quadratic equation so that you end up with the possible values of x.

So the final answer is the same. Step 1: Write the quadratic in the correct form, since the leading coefficient is not a 1, you must factor the 2 out of the first two terms. Step 2: Fill in the first blank by taking the coefficient (number) from the x-term (middle term) and cutting it in half and squaring it.

You know by now how to solve a quadratic equation using factoring. Another way of solving a quadratic equation is to solve it graphically. The roots of a quadratic equation are the x-intercepts of the graph.

Often, the simplest way to solve "ax2 + bx + c = 0" for the value of x is to factor the quadratic, set each factor equal to zero, and then solve each factor. But sometimes the quadratic is too messy, or it doesn't factor at all, or you just don't feel like factoring.

Step 1: To use the quadratic formula, the equation must be equal to zero, so move the –5 back to the left hand side. Step 2: Identify a, b, and c and plug them into the quadratic formula. In this case a = –3, b = 6, and c = 5. Step 3: Use the order of operations to simplify the quadratic formula.

Now we can solve a Quadratic Equation in 5 steps: Step 1 Divide all terms by a (the coefficient of x2). Step 2 Move the number term (c/a) to the right side of the equation. Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation.

Factoring is a step taken towards solving a quadratic equation. ... You cannot factor them, the only way to find the roots then, is by using the quadratic formula. Suppose you factor the quadratic polynomial as and . Then set them equal to zero and solve for , you will have and .

Set the equation equal to zero for each set of parentheses in the fully-factored binomial. For 2x^3 - 16 = 0, for example, the fully factored form is 2(x - 2)(x^2 + 2x + 4) = 0. Set each individual equation equal to zero to get x - 2 = 0 and x^2 + 2x + 4 = 0. Solve each equation to get a solution to the binomial.

Begin by multiplying both sides by the LCD, x(x+1) x ( x + 1 ) . After distributing and dividing out the common factors, a quadratic equation remains. To solve it, rewrite it in standard form, factor, and then set each factor equal to 0. Check to see if these values solve the original equation.
