Step 1: To use the quadratic formula, the equation must be equal to zero, so move the –4x 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 = 4, and c = 8. Step 3: Use the order of operations to simplify the quadratic formula.

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.

Some quadratic expressions can be factored as perfect squares. For example, x²+6x+9=(x+3)². However, even if an expression isn't a perfect square, we can turn it into one by adding a constant number. For example, x²+6x+5 isn't a perfect square, but if we add 4 we get (x+3)².

To factor a trinomial in the form x2 + bx + c, find two integers, r and s, whose sum is b and whose product is c. Rewrite the trinomial as x2 + rx + sx + c and then use grouping and the Distributive Property to factor the polynomial. The resulting factors will be (x + r) and (x + s).

The quadratic formula. The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) .

Every difference of squares problem can be factored as follows: a2 – b2 = (a + b)(a – b) or (a – b)(a + b). So, all you need to do to factor these types of problems is to determine what numbers squares will produce the desired results. Step 3: Determine if the remaining factors can be factored any further.
