Using the limit definition of the derivative, you have

Simplify the numerator:
(2<em>x</em> ² + 4<em>x</em> + 7) - 37 = 2<em>x</em> ² + 4<em>x</em> - 30
… = 2 (<em>x</em> ² + 2<em>x</em> - 15)
… = 2 (<em>x</em> + 5) (<em>x</em> - 3)
Then

For your second question in the comments, if <em>f(x)</em> = -2<em>x</em> ² + 3<em>x</em> - 7, then by the definition of the derivative, you have

Simplify the numerator:
(-2 (<em>x</em> + <em>h</em>)² + 3 (<em>x</em> + <em>h</em>) - 7) - (-2<em>x</em> ² + 3<em>x</em> - 7)
… = (-2<em>x</em> ² - 4<em>xh</em> - 2<em>h</em> ² + 3<em>x</em> + 3<em>h</em> - 7) - (-2<em>x</em> ² + 3<em>x</em> - 7)
… = -4<em>xh</em> - 2<em>h</em> ² + 3<em>h</em>
Now compute the limit:

Answer:
$950
Step-by-step explanation:
26% less than the regular price = 74%
set up the dimensions as:
part/whole = part/whole
$703 goes in part 74% goes in part
703/? = 74%/100%
Then multiply 100 by 703
100 x 703 = 70300
Finally divided by 74
70300 divided by 74 = 950
••••••••••••••••••••••••••••••••••••
The regular price = $950
703/950 = 74%/100%
