Answer:

see explanation

Step-by-step explanation:

Given

x² - 6x + 7 = - 13

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 3)x + (- 3)² + 7 = - 13 + (- 3)²

x² - 6x + 9 + 7 = - 13 + 9

(x - 3)² + 7 = - 4

With replacement, each draw has a probability of
9 pink out of 18 total number of chips.

Therefore, by the multiplication rule, the probability of having both draws picking a pink is 
P(pink,pink) = (9/18)*(9/18) = 81/324   [ = 1/4 ]
or
P(pink,pink) = \frac{9}{18}*\frac{9}{18}=\frac{81}{324}
