Question

If you divide one root of the equation 4x^2 - bx - 27 = 0, what do you get?

A) 4
B)b
C)-4
D) 27

Answer 1

To find one root of the quadratic equation 4x² - bx - 27 = 0, use the quadratic formula and substitute the values of a, b, and c from the equation. The value of x represents one of the roots.

Step-by-step explanation:

To find one root of the quadratic equation 4x² - bx - 27 = 0, we need to use the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

Comparing this formula with the given equation, we have a = 4, b = -b, and c = -27.

1. Substitute the values of a, b, and c into the quadratic formula.
2. Solve for x using the positive sign before the square root.
3. The value of x represents one of the roots of the equation.

In this case, we don't have a value for b, so we cannot find the specific root. Therefore, the answer is None of the above (E).
