Write a quadratic function from its zeros

Full solution

Q. Write a quadratic function with zeros

6

and

-2

.

\newline

Write your answer using the variable

x

and in standard form with a leading coefficient of

1

.

\newline

f(x) =

______

Identify Zeroes: Zeroes are $6$ and $-2$ , so the factors are $(x - 6)$ and $(x + 2)$ .
Factorize: $f(x) = (x - 6)(x + 2)$ because the leading coefficient is $1$ .
Expand: Now we expand: $f(x) = x(x + 2) - 6(x + 2)$ .
Multiply $x$ : Multiplying $x$ with $(x + 2)$ gives $x^2 + 2x$ .
Multiply $-6$ : Multiplying $-6$ with $(x + 2)$ gives $-6x - 12$ .
Combine Terms: Adding them up: $f(x) = x^2 + 2x - 6x - 12$ .
Final Result: Combine like terms: $f(x) = x^2 - 4x - 12$ .
