Question

Which point is an x interception of the quadratic function f(x)=(x-8)(x+9)

Answer 1

I got (-9,0).

Explanation:

Answer 2

`f(x)=(x-x_1)(x-x_2)\\\\(x_1,\ 0),\ (x_2,\ 0)-x\ interceptions`

`\text{We have}\ f(x)=(x-8)(x+9)=(x-8)(x-(-9))\\\\\text{therefore your answer is:}\\\\(8,\ 0),\ (-9,\ 0)`
