Using the discriminant, the quadratic equation that has complex solutions is given by:
x² + 2x + 5 = 0.
<h3>What is the discriminant of a quadratic equation and how does it influence the solutions?</h3>
A quadratic equation is modeled by:
y = ax² + bx + c
The discriminant is:
The solutions are as follows:
- If
, it has 2 real solutions.
- If
, it has 1 real solutions.
- If
, it has 2 complex solutions.
In this problem, we want a negative discriminant, hence the equation is:
x² + 2x + 5 = 0.
As the coefficients are a = 1, b = 2, c = 5, hence:

Answer: 10.5 feet
Step-by-step explanation:
From the question, we are informed that Marcel is purchasing a board to build a bookcase he wants to divide the board into 1.75-foot sections and that he needs 6 sections.
The size of the board that Marcel need will be calculated by multiplying 6 by 1.75 foot. This will be:
= 6 × 1.75
= 10.5 feet

Answer:
7
Step-by-step explanation:
x * x = 7x
7 x 7 = 7 x 7
49 = 49
so if x is 7, the equation is true...
