What are the exact solutions of x2 − 5x − 1 = 0 using x equals negative b plus or minus the square root of the quantity b squared minus 4 times a times c all over 2 times a?
a x = the quantity of 5 plus or minus the square root of 29 all over 2
b x = the quantity of negative 5 plus or minus the square root of 29 all over 2
c x = the quantity of 5 plus or minus the square root of 21 all over 2
d x = the quantity of negative 5 plus or minus the square root of 21 all over 2
Answer:
a
Step-by-step explanation:
The explanation is attached below.
The correct answer is (a) x = (5 ± √29) / 2.
To find the solutions of the quadratic equation x^2 - 5x - 1 = 0 using the quadratic formula, we can identify the values of a, b, and c:
a = 1
b = -5
c = -1
Plugging these values into the quadratic formula:
x = (-b ± √(b^2 - 4ac)) / (2a)
Substituting the values of a, b, and c:
x = (-(-5) ± √((-5)^2 - 4(1)(-1))) / (2(1))
x = (5 ± √(25 + 4)) / 2
x = (5 ± √29) / 2
Therefore, the solutions to the equation x^2 - 5x - 1 = 0 are x = (5 + √29) / 2 and x = (5 - √29) / 2, which corresponds to option (a).
