BIG IDEAS

  • I can design the track of a roller coaster, determine the sloped curve of an exit ramp, trace the free falling path of a skydiver, and understand the mechanics of controllers like autopilot, cruise control, and a living room thermostat.
  • I will apply mathematical processes for basic operations to algebraic expressions and divide algebraic terms out of algebraic expressions.


UNDERSTANDING THE STANDARD

  • Computational skills applicable to numerical fractions also apply to rational expressions involving variables.
  • Radical expressions can be written and simplified using rational exponents.
  • Only radicals with a common radicand and index can be added or subtracted.
  • A relationship exists among arithmetic complex fractions, algebraic complex fractions, and rational numbers.
  • The complete factorization of polynomials has occurred when each factor is a prime polynomial.
  • Pattern recognition can be used to determine complete factorization of a polynomial.

ESSENTIALS

The student will use problem solving, mathematical communication, mathematical reasoning, connections, and representations to

All.1c1  Convert from radical notation to exponential notation, and vice versa.  Solve an equation containing a radical expression.
