Answer:
Step-by-step explanation:
Given equation is,
x² + (p + 1)x = 5 - 2p
x² + (p + 1)x - (5 - 2p) = 0
x² + (p + 1)x + (2p - 5) = 0
Properties for the roots of a quadratic equation,
1). Quadratic equation will have two real roots, discriminant will be greater than zero. [(b² - 4ac) > 0]
2). If the equation has exactly one root, discriminant will be zero [(b² - 4ac) = 0]
3). If equation has imaginary roots, discriminant will be less than zero [(b² - 4ac) < 0].
Discriminant of the given equation = 
For real roots,

p² + 2p + 1 - 8p + 20 > 0
p² - 6p + 21 > 0
For all real values of 'p', given equation will be greater than zero.

Answer:
Total earned= $850
Step-by-step explanation:
Giving the following information:
David makes 17 dollars in an hour and works 25 hours each week Linda makes 25 dollars in an hour and works 17 hours.
<u>To calculate the total earned, we need to use the following formula:</u>
Total earned= 17*25 + 25*17
Total earned= $850
