You could solve this problem by either: Factoring or by using the Quadratic Formula.
SOLVING BY FACTORING STEPS
<em>STEP 1:</em><em> Move (2x−1)(x+1) to the left side of the equation by subtracting it from both sides.</em>
<em />
<em>STEP 2:</em><em> Simplify 2x^2+3x−(2x−1)(x+1).</em>
<em />
<em>STEP 3: </em><em>Simplify each term.</em>
<em />
<em>STEP 4: </em><em>Simplify by adding terms.</em>
<em />
<em>STEP 5:</em><em> Subtract 1 from both sides of the equation.</em>
<em />
<em>STEP 6: </em><em>Divide each term by 2 and simplify.</em>

<em><u>The expression that describes the number of tickets won by Lily is:</u></em>
a = 8 + 4.5c where "a" is the number of tokens won by Lily and "c" is the number of tokens won by Ben
<em><u>Solution:</u></em>
Given that Lily, Louis, and Ben went to an arcade and won tokens for prizes
Let "a" be the number of tokens won by Lily
Let "b" be the number of tokens won by Louis
Let "c" be the number of tokens won by Ben
<em><u>Given that Louis won 4.5 times as many tokens as Ben</u></em>
So we can frame a equation as:
number of tokens won by Louis = 4.5 times as many tokens as Ben
number of tokens won by Louis = 4.5 x number of tokens won by Ben
b = 4.5c
<em><u>Given that Lily won 8 more tokens than Louis</u></em>
number of tokens won by Lily = 8 + number of tokens won by Louis
a = 8 + b
Substituting the value of b = 4.5c in above expression
a = 8 + 4.5c
Thus the expression that describes how many tokens Lily won is found
