Q. Write a quadratic function with zeros 8 and −5.Write your answer using the variable x and in standard form with a leading coefficient of 1.f(x)=______
Identify Zeros: Zeros are 8 and −5, so factors are (x−8) and (x+5).
Factorize:f(x)=(x−8)(x+5), cuz we multiply the factors together.
Expand and Simplify:f(x)=x(x+5)−8(x+5), we distribute −8 across (x+5).
Combine Like Terms:f(x)=x2+5x−8x−40, now we combine like terms.
Standard Form:f(x)=x2−3x−40, and that's the standard form.
