Find a quadratic function with roots x = 8 and x = 9.

The quadratic function with roots x = 8 and x = 9 is given as

Solution:

Given that the roots of function are x = 8 and x = 9

We need to find the quadratic function

Now, we know that, quadratic equation is given by

where a and b are roots of that quadratic equation.

Here a = 8 and b = 9

By substituting the "a" and "b" values in general quadratic function we get,

Hence the required quadratic function is found out

Step-by-step explanation:

First lets put these in one form of number type. For example, decimals, fractions, and percentages. In this case I like decimals, So I will do decimals.

0.12 is already a decimal

1/8 Divide one divided by 8 Which is equal to 0.125

0.135 Is already a decimal

13%  is simplified to 0.13. in order to simplify you need to count the numbers and put it behind the numbers for example 12 percent or 12% count how many numbers there are (two numbers) then put the decimal there 12 to 1.2 then to (.12). next put them in order.

and your answer is:

0.135, 0.13, 0.125, 0.12
