In Exercises 11 to 18, determine the values of a, b, and c that are needed in order to use the Quadratic Formula. Choose a > 0 ( x + 5 ) ( 2 x − 7 ) = 117

To determine

To find:

To determine the values of a, b, and c that are needed in order to use the Quadratic Formula

Explanation

Consider the following equation,

(x+5)(2x7)=117.

First multiply the terms inside the bracket to get the following,

(x+5)(2x7)=1172x27x+10x35=1172x2+3x35=117

Subtract 117 on both sides to get the following,

2x2+3x35117=1171172x2+3x152<
