Question

What are zeros of the quadratic expression.

a) x = 1 or x = 5x
b)x = 1 or x = −5x
c)x = −1 or x = 5x
d) x = −1 or x = −5

Answer 1

The zeros of the quadratic expression x² + 0.0211x - 0.0211 = 0 are approximately x = 0.9997 and x = -2.9997

Step-by-step explanation:

The zeros of a quadratic expression are the values of x that make the expression equal to zero. In this case, the quadratic expression is given by x² + 0.0211x - 0.0211 = 0. To find the zeros, we can use the quadratic formula:

x = (-b ± √(b² - 4ac))/(2a)

Plugging in the values a = 1, b = 0.0211, and c = -0.0211 into the quadratic formula, we get:

x = (-0.0211 ± √(0.0211² - 4(1)(-0.0211)))/(2(1))

Simplifying further, we find that the zeros of the quadratic expression are approximately x = 0.9997 and x = -2.9997
