Consider the equation ax^2 bx 5=0 where a, b,c are rational numbers and the quadratic has 2 distinct zeros. if one zero is irrational, the other 0 is

The other zero is also  irrational. ( the complex conjugate of the first zero)

Step-by-step explanation:

We are given a quadratic equation as:

where a,b and c are rational numbers.

Also it is given that the quadratic has 2 distinct zeros and one of it's zero is irrational.

" We know that for a polynomial equation with rational coefficients if it has one irrational zero then the conjugate pair of that zero is also an zero of the same polynomial equation "

Hence, in this case it is a quadratic equation such that one of it's zero is irrational, hence the other zero is also irrational.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
