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.
For Exercises 11–12,

- For Exercises 115–120, factor the expressions over the set of complex numbers. For assistance, consider these examples. • In Section R.3 we saw that some expressions factor over the set of integers. For example: x - 4 = (x + 2)(x – 2). • Some expressions factor over the set of irrational numbers. For example: - 5 = (x + V5)(x – V5). To factor an expression such as x + 4, we need to factor over the set of complex numbers. For example, verify that x + 4 = (x + 2i)(x – 2i). 115. а. х - 9 116. а. х? - 100 117. а. х - 64 b. x + 9 b. + 100 b. x + 64 118. а. х — 25 119. а. х— 3 120. а. х — 11 b. x + 25 b. x + 3 b. x + 11arrow_forwardIn Exercises 11–14, use a product-to-sum formula to find the exact value.
