anonymous · Answer

ok so you are gonna start with expanded form writing your equation out like this y=x(x+1)(x-2)

anonymous · Answer

then you need to multiply all of it out to turn it into a polynomial

anonymous · Answer

which will give you $$x^3-x^2-2x$$

anonymous · Answer

does this help? and do you understand how I did everything?

mathstudent55 · Answer

A polynomial with roots a, b, and c, is (x - a)(x - b)(x - c)
Use your given roots for a, b, and c.
Write the three binomials, and multiply them together.

cutiekawdfi · Answer

how did you multiply it and get that answer

anonymous · Answer

so you have to distribute them out. so you start by distributing x into the x+1 which will give you x^2+x. make sense so far?

cutiekawdfi · Answer

yes

anonymous · Answer

ok so then you are left with 2 binomials $$(x^2+x)(x-2)$$ then you multiply them together as two binomials, which is how I got to my final answer

i see (: thank you so muchh <3

no problem!(:
