Mathematics
1 answer:

Answer:

x = -3   or   x = 3

Step-by-step explanation:

Subtract 9 from both sides.

x^2 - 9 = 0

Factor the left side. There is no common factor of the terms. It is a binomial which is the difference of two squares, so it factors into the product of a sum and a difference.

(x + 3)(x - 3) = 0

Set each factor equal to zero.

x + 3 = 0   or   x - 3 = 0

Solve each equation.

x = -3   or   x = 3

Step-by-step explanation:

Given that :

Player with the lowest score wins ;

Vanessa's score = - 3 5/8

Zack's score = - 3 2/3

Converting to decimal:

Vanessa :

-3 5/8 = - 29 /8 = - 3.625

Zack:

-3 2/3 = - 11/3 = - 3.666

Comparing the scores :

From the negaryce side of a number line :

-3.666 comes before - 3.625, hence, - 3.666 is lower or lesser than - 3.625

-3.666 < - 3.625, hence Zack won
