Sally has the following question on her EOC test. The graph of the function h(x)=x^3-9x+10 has a real zero when x=2 What are the other real zeros? Help guide Sally to the correct solution. Select the first step that Sally should do from the choices below: A Set up a long division problem with x^3+0x^2-9x+10 as the dividend and x-2 as the divisor. B Graph it in Desmos and pick the points that look correct. C Set up a long division problem with x-2 as the dividend and x^3+0x^2-9x+10 as the divisor. D Throw her laptop in anger across the room b/c math is stupid.

D Throw her laptop in anger across the room b/c math is stupid.

Answer 1

The first step that Sally should take is to set up a long division problem with

as the dividend and

as the divisor. This will help her find the quotient, which can then be factored further to find the other real zeros.So, the correct choice is:A) Set up a long division problem with

as the dividend and

as the divisor.
