#2 Explain why the computational result in each of the following two parts is wrong and give the correct answers. a. 3(x - 7) = 3x-7 b) ( x + h ) 2 = x2 + h2 c) (3x) 2 = 3x2 (2) Simplify rational function Definition: The quotient of two polynomials is a rational expression P(x) Q ( x )' where P(x) and Q(x) are polynomials. The restriction is the denominator cannot be 0; i.e., Q(x) # 0. #3 State the restriction and simplify each rational expression 4x 4 a. b. x-4 (x-1) (x+1)
