One of the roots of the equation 10x2−33x+c=0 is 5.3. find the other root and the coefficient c.

1. The other root is

2. c=-106

Step-by-step explanation:

The given equation is .

If is a solution to the given quadratic equation, then must satisfy this equation.

We now substitute into the given equation to obtain;

.

Comparing to the general equation;

, we have a=10, b=-33 and c=-106.

Recall the quadratic formula;

We now use the quadratic formula to obtain;

This implies that;
