What are the zeros of the quadratic function f(x) = 2x2 – 10x – 3?

 are zeroes of given quadratic equation.

Step-by-step explanation:

We have been a quadratic equation:

We need to find the zeroes of quadratic equation

We have a formula to find zeroes of a quadratic equation:

General form of quadratic equation is

On comparing general equation with b given equation we get

a=2,b=-10,c=-3

On substituting the values in formula we get

Now substituting D in   we get

Therefore,

A quadratic equation is in the form of .......[1]

then the solution for this equation is given by:

Given the quadratic equation:

To find the zero of the given equation.

Set f(x) = 0

then;

On comparing with equation [1] we have;

a = 2, b = -10 and c = -3

then;

⇒

⇒

⇒

Simplify:

Therefore, the zeros of the given quadratic equation are;

and

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

first one because it can't have a fraction in it
