How to multiply the polynomial (4p-1)(4p-1)

(4p-1)(4p-1)
16p² - 4p - 4p + 1
16p² -8p +1

Hope this helps!

First multiply 4p by 4p from the other parenthesis. Then multiply the same 4p with -1 from the second parenthesis. Then do the same with the -1 from the first parenthesis.
Then you get:
4p×4p + 4p×(-1) + (-1)×4p + (-1)×(-1) =
16p^2 - 4p - 4p + 1 =
16p^2 - 8p + 1.

Step-by-step explanation:

To answer this, set the function y = 9.5x + 62.1 = to 138.1 and solve the resulting equation for x:

9.5x + 62.1 = 138.1

We must isolate x.  Start this process by subtracting 62.1 from both sides of this equation, obtaining:

9.5x = 76

Now divide both sides of this equation by 9.5:

x = 76/9.5 = 8
