Standard form of a quadratic equation: Yesterday when we graphed quadratic equations we used the same x values in our tables because the equations we graphed did not have any “b” values. If you were to graph y = x2 + 6x + 8 and used the same x values as we did yesterday, what kind of shape would the graph make? y = x2 + 6x + 8

Squaring both sides of an equation is a typical example of an irreversible step; another is multiplying both sides of the equation by a quantity that might be zero (see examples). With an understanding of solving equations as a reasoning process, students can organize the various methods for solving different types of equations into a coherent ...

Step 2: Factor the quadratic equation. Step 3: After the problem has been factored we will complete a step called the “T” chart. Create a T separating the two ( ). Step 4: Once ( ) are separated, set each ( ) = to 0 and solve for the variable. Step 5: Check each of the roots in the . ORIGINAL .
Factoring Quadratics
Thus if one of the factors of a quadratic is zero then the whole thing is zero and that is the setup! Solving Quadratic Equations. Step 1: Put the equation in standard form. Step 2: Factor the polynomial. Step 3: Set each term that contains a variable equal to zero and solve for the variable. Step 4: Write the solution as: variable = or. variable =
