True or false If false replace underlined words or expressio

True or false. If false replace underlined word(s) or expressions to make a true statement

Solution

1)FALSE

(-3x³ +5x +2)/(x²-1)

long division

x²-1)...-3x³ +5x +2..(-3x

..........-3x³ +3x ..,

..........⁽⁺⁾....^(-)...............

..................2x+2

(-3x³ +5x +2)/(x²-1) =(-3x) +(2x+2)/(x²-1)

(-3x³ +5x +2)/(x²-1) =(-3x) +(2(x+1))/((x+1)(x-1))

(-3x³ +5x +2)/(x²-1) =(-3x) +(2/(x-1))

2)FALSE

if f(-x)=-f(x) , the f is odd function for all x in its domain
