Investigation 5: Developing and Analyzing the Quadratic Formula

Test yourself (Answers)

To solve this equation multiply through by the common denominator of all the fractions, viz. (2 - x)(x + 3)

Substitute a = 5, b = 6 and c = -22 into the quadratic formula and simplify:

The roots of the equation are

( Note: The radical in the formula must be simplified when solving equations: and the expression reduced as much as possible for stating the roots )
