Question

Ok I’m stuck please help

Answer 1

First move the 13 to the left by subtracting 13 from both sides and setting the 'now expression' equal to zero

p² - 12p - 13

Do the opposite of FOIL (for you are trying to find the numbers being FOILed)

p² - 12p - 13

Find the multiplies of the outside numbers/variables, that, when added (or subtracted, will give you the inside expression

p² - 12p - 13
p             -13
p               1

(p - 13)(p + 1)

Set these two expressions equal to zero

p - 13 = 0
p - 13 (+13) = 0 (+13)
p = 13

p + 1 = 0
p + 1 (-1) = 0 (-1)
p = -1


Your answers: p = -1, 13


hope this helps
