Question:

Part A: How do you factor trinomials? Use 2x^3 - 16x^2 - 18x to explain the process.



Part B: How can we check the binomial factors to verify that they are truly factors?

Answer 1

Answer:

See below

Step-by-step explanation:

You pull-out what is common.

2$x^{3} -16x^{2} -18x$

$2x(x^{2} -8x-9)$

2x(x-9)(x+1)

To verify, set each answer = 0

2x = 0, x=0

x-9 = 0, x=9

x+1 = 0,  x=-1

Now, plug each value back into the equation and make sure each one equals 0.
