2. Example: x^2-10x+16=0 (x−2)(x−8)=0 x−2=0 or x−8=0 x=2 or x=8
3. Solve Quadratic Equations by Factoring. When a polynomial is set equal to a value (whether an integer or another polynomial), the result is an equation. An equation that can be written in the form ax2 + bx + c = 0 is called a quadratic equation.

5. The formula that should be used:
6. 2x^2=7x+6 Step 1: To use the quadratic formula, the equation must be equal to zero, so move the 7x and 6 back to the left hand side. Step 2: Identify a, b, and c and plug them into the quadratic formula. In this case a = 2, b = –7, and c = –6. Step 3: Use the order of operations to simplify the quadratic formula.
