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 \( x^{3} + 0x^{2} - 9x + 10 \) as the dividend and \( x - 2 \) as the divisor. This will help her find the quotient, which can then be factored further to find the other real zeros.<br /><br />So, the correct choice is:<br />A) Set up a long division problem with \( x^{3}+0 x^{2}-9 x+10 \) as the dividend and \( x-2 \) as the divisor.
