Find two numbers that multiply to c and add t2 b 2. When dealing with binomials such as 9x –16 you just take the square root and multiply it by the congruent 2  Factor trinomials a x +bx+c 2 1. Trial and error method ex: 3x – x–2= (3x+2 )x–1 ) STAT 09/08 Rational expressions  Simplify expressions into lowest terms: find common factor and cancel ex: 8 18x 3x 24x 7= 4  You can only cancel factors, not sums  You can only cancel 1 for 1  Multiply expressions and simplify find common factor and cancel until in lowest form, then multiply across  Sometimes you will have to factor to cancel  Divide expressions and simplify: factor, flip, and multiply  Whenever you divide fractions, multiply by the reciprocal  Always check your factoring! Exponents and Radicals 1. Properties of exponents n m n+m  a xa =a an n−m  m=a a  a =1 −n n  a =1/a m  (an) =a nm n pm nm pm  (a xb ) =a xb 2. Radicals and Rational exponents m √ am ¿  = a n
