In Exercises 126–129, determine whether each statement is true
or false. If the statement is false, make the necessary change(s) to
produce a true statement.
126. Once a GCF is factored from 6y – 19y + 10y“, the
remaining trinomial factor is prime.
127. One factor of 8y² – 51y + 18 is 8y – 3.
128. We can immediately tell that 6x? – 11xy – 10y? is prime
because 11 is a prime number and the polynomial contains
two variables.
129. A factor of 12x2 – 19xy + 5y² is 4x – y.
In Exercises 34–37, solve each polynomial equation.
34. 3x? = 5x + 2
35. (5x + 4)(x – 1) = 2
36. 15x? – 5x = 0
37. x - 4x2 - x + 4 = 0
