Answer:
Step-by-step explanation:
<u>Roots:</u>
<u>The equation:</u>
- (x - x₁)(x - x₂) = 0
- (x - (-3))(x - 5) = 0
- (x + 3)(x - 5) = 0
- x² + 3x - 5x - 15 = 0
- x² - 2x - 15 = 0

Answer:
Rectangle has both line and rotational symmetry
The Z has line symmetry
The trapezoid lookin thing has none
The quadratic equation has two solutions if b^2 - 4ac > 0
Given the equation ax^4 + bx^2 + c=0
Substitute into the formula to have:
The equation becomes aP^2 + bP + c = 0
For us to have a unique solution, the discriminant b^2 - 4ac must be greater than zero. Hence the quadratic equation has two solutions if b^2 - 4ac > 0
