In this lesson, students learn to solve quadratic equations in the form
ax^2 + bx + c = 0 using the quadratic formula, which states that x = -b plus or minus the square root of b^2 -- 4ac over 2a. For example, to solve the equation x^2 -- 3x -- 8 =... 0, since a = 1, b = -3, and c = -8, the quadratic formula states that x = 3 plus or minus the square root of (-3)^2 -- 4(1)(-8) over 2(1). Simplifying on the right side of the equation, x = 3 plus or minus the square root of 9 + 32 over 2, or x = 3 plus or minus the square root of 41 over 2, which is the final answer.
