Answer:</h3>
1. Solutions: x = 3.4, 10.6
2. Solutions: ,
3. Solutions: x = -1, 11
<h3>
Step-by-step explanation:</h3>
Quadratic formula:
Quadratic equation: ax² + bx c = 0, where a ≠ 0
1. x² - 14x + 36 = 0
a = 1, b = -14, c = 36
Substitute the given values into the formula:
Separate into two cases:
and
2. x² + 7x + 16 = 0
a = 1, b = 7, c = 16
Substitute the given values into the formula:
Imaginary number rule: For any positive real number "k",
Notes: Two imaginary solutions indicate that the graph will not intersect the x-axis. As a result, it has no real roots.
Separate into two cases:
3. x² - 10x - 11 = 0
a = 1, b = -10, c = -11
Substitute the given values into the formula:
Separate into two cases:
and
